It is already playable, even if I don't test if the IA player work well in modern period.
I have not updated the units description in the help of the game, so I give here some :http://i49.tinypic.com/2w3dfr6.jpg
I have classified them in order to appearance. Each *** lines are major breaknought that make hitpoint x2, and add 1 to firepower (not always, but is the principle).
galley -> coastal first boat. can travel in river.
trireme -> coastal war galley. fast and strong attack. can travel in river.
sail -> high sea transport boat. slow, weak, but can avoid trireme with high see escape.
caravels -> high sea more large boat than sail. bigger defense against trireme boarding, but always also slow and quite weak.
carracks ->big caravels with high castle in prow and stern for bowmen. High deck able too defend well against triremes boarding. but not very good for attack other boats.
Galleon ->first boat with gunpowder, no more need of trireme, finally outclassed. It is the first boat since galley can fight and transport as well.
Frigate ->first line heavy galleon, design for war and sea superiority. strong but expensive.
Corsairs ->fast ship, quite furtive, no need of shield support but money supports. There can't bear attacked by frigate but they can avoid them and strike by surprise. good for fight down those slow cheap galleon.
steam frigate ->less numerous canon but more accurate and powerful, and steam engine. All of these make those boats able to outclass old frigates.
ironclad ->intermediate small armored boat. unable to catch theirs equals (more defense than attack) but lethal for steam frigate. cheap, small, coastal, no transport.
dreadnought (cruisers) ->first modern cruisers. reduce all previous boat too training trajets.
cargo ->coal engine cargo. no weapons. cheap as "liberty ships".
u-boat ->first submarines, strikes with torpedoes. there are furtive, cheap, powerful, and fast but very fragile. (it's an false idea that submarine's are slow. there are always be as fast as their targets, often faster, even in dive). so yes, these unit make cruisers quite useless, and are cargo's nemesis. it's historical fact. also they can carry spy. cannot fight others submarines.
destroyers->cheaper than cruisers, but not very weaker. they use big torpedoes for fight vs cruisers, and medium canon against boats smaller than us. faster than old cruisers. useful for submarine's hunt.
battleships->state of the art heavy cruisers. very powerful and highly armored, but expensive...
carrier->first carriers can deploy only small aircrafts (fighters and small bomber). but they're already more useful than battleships. expensive. can not carry jet aircraft, but can carry helicopters.
nuclear submarines->state of the art submarines. they are very powerful, furtive, well protected, fast. they can carry missiles. they can fight other submarines with hunter seeker's heat torpedoes.
nuclear carrier->they can carry jet planes(only smaller ones).
modern frigate->boat for missile fighting. costless than submarines, but more spotable. can carry one helicopter. and missiles, obviously.
modern cargo->diesel engine modern cargo. outclass old coal's one by fast and capacity.
well, I think we cover all the naval history and improvement with this. Each "***" mean that older can hardly striking vs newer. even, as ex, old war boat vs modern transport boat. a trirem as no chance vs a coal cargo, even if she's success too catch him. it the same with u-boat vs modern frigate or nuclear submarines, etc.LANDS :
3 settlers for follow eras. each as better defense and more hitpoint, too reproduce the fact that the high tech settler cannot caught by antic warriors, even if there are civilians : pioneers as hunting weapons, for example. even alexander's phalanx can do nothing vs american pioneers which travel with rifles... (even if we assume phalanx are not too afraid, and don't flee away at first strike back).
3 workers, same idea.
2 diplomats, and a spy. maybe the modern diplomats, I call "ambassador" can have more use than diplomat but I don't have much idea.
3 merchants, same idea than workers and settlers.SPECIAL :
marines -> elite infantry. not just "amphibious". I think they can be also "city buster" if I have confirmation this can work. anyway many infantry unit has amphibious flag (legion, and all after musketeer)
paratroopers -> elite airborne infantry. city buster also, and furtive. they have not very strong offense, but can defend themselves and produce ZOC, for disturb enemy moving and help conventional army make his offensive. they can be used for defend encircle area, also. I want to make them well defend against aircraft, but I think the AEGIS flag is too much.
partisans->identical current one, except they're "bad city attacker". can not be too used as offensive troops. they should be furtive, also.
fanatics->idem current. bad city defender, maybe "missile" flag, for make them suicide's squads.
cruise missiles->ground to ground medium range missile.
nuclear missile->intercontinental nuclear headed missile.
intercontinental missile->idem with high explosive non-nuclear head.
strike missile->short range missile for anti-aircraft purpose. work also against boat or other unit.LAND :
warriors -> hunter packed for military usage. neolithic weapons...
horsemen -> horsemen hunter, weak but fast. (1 tile speed but lighter)
phalanx -> bronze's age multipurpose warriors. they're good as defence even as attack. (remember what's alexander did with them). I choice too mix all foot warriors of this era (archer, hoplites, skirmirchers, etc.) because they are also used mixed actually. a lonely phalanx does not make much sense, and the purpose of civ is not to make a highly details tactical game, but strategical I think.
horsemen -> war trained bronze age horse men. not very strong but fast. (not strong because they haven't stirrups) (1 tile speed, lighter)
chariot -> without the discover of stirrups, the only way for use the speed of horses, is to use chariot for javelin launcher. fast, but only useful in plains. (2 tiles speed, not lighter)
catapult -> strong siege machine. break city wall. expensive, defensles and slow.
===> here there are bronze's age units. one infantry, one fast horse for hunting and scouting, one heavy mounted for rule the plains battlefields, and one war machine for city assault. In my mind, all horses unit are "IZOC", so they are used in battle to overrun slower infantry unit. But infantry are cheaper, and often more powerful. infantry are used as well for attack or defend, but in this era, there are better for attack (unless beyond city walls). heavy mounted unit has same stats than infantry, but more movement. cost very most. maybe I will make then "bad city defender" (how use a chariot behind city wall ?).
legion -> early iron age warriors. more powerful for attack than phalanx. they can also make amphibious attack from trireme.
horsebowmen -> lack of stirrups made the choice of fill horsemen with small bow. not very powerful but fast and useful for hunting down lonely injured warriors.
bow chariot -> chariot lightweight, faster than older's. fill with two men, one for drive, and one for strike with bow. useless in difficult terrains.
siege tower -> strong siege unit. slow and expensive. can defend also. maybe prefer old catapult for poor defended city with walls.
===>a new version for each unit role. the older one are replace, except catapult (less effective against legion, but siege tower very very expensive).
soldier -> middle iron age soldier. more defense, but less attack. pikemen. costless than legions (which can be always product)
paladin -> replace horsebowmen. (not historically accurate but I like the picture)
knight -> mounted soldier version. replace chariot. stirrups at last discovered give mounted soldier high velocity charge capability, and they now use long pike and no more bow.
trebuchet -> powerful siege machine. very expensive. replace catapult.
===>in middle iron age, it is more easy to defend than to attack. trebuchet are essential for strike city. without, you should better do long time siege with cheap soldiers than bloody assault.
hallebardier -> last iron age soldier, some early gunpowder weapon for us. from this point, all infantry unit have "pikemen" flag.
fedaykins -> replace paladins. fast horsemen without armor, using sword and early gun weapons.
bombard -> first gunpowder canon are not very powerful. they're throw stone bullets. less dangerous than trebuchet, but costless.
===>this age is a turning point. bad time for horsemen...
musketeer -> well defended, but nearly unable too attack other musketeers. they can do amphibious attack from galleon or frigate, and all later infantry can do the same.
hussar -> mounted musketeers. from this point there is no more difference between fast light horsemen and heavy's. heavy's armored horsemen vanished since real usable gunpowder weapons.
canon -> first real canon. essential for destroy musketeers in defence position. vulnerable to hussar.
===>we are goes toward "war position". it is more and more easy to defend and difficult to attack because power of guns.
fusilier -> rifle are always one shot, but can be filled by cylinder head whose give faster shot.
cavalry -> they're not use heavy rifle but small one likes winchesters. small bullets and range, but higher fire rate.
artillery -> canon are more accurate and fire explosives shell. really dreadful. the golden age of war position and bloody mass going-to-death assaults.
tank -> early armor, like WWI one's. not very good, but useful as new "heavy armored horsemen". cannot destroy city walls.
infantry -> WWII like soldiers. they are better than fusilier, and move faster with the generalization of trucks. this is now mobile war.
half-track -> light armored fast vehicles. used for scouting and support side's main offensives.
armor -> real armor, they're are fast, powerful, well protected. but expensive. they're outclass old tanks. destroy city walls, as well as other mobile guns vehicles.
artillery -> powerful and cheap. used with lot infantry, after strong armor blitzkrieg for destroy cores of resistances.
canon automobile -> armor with bigger gun but immobile turret. cheap than armor. can be used as armor killer, or speed artillery to follow armor fast pierce through enemy territory. need escort.
heavy armor -> bigger armor, like 1960's ones.
anti-aircraft armor -> armor with anti air guns, for escort armor.
MBT (main battle tank) -> state of the art armor. they are electronic assisted, well protected with reactive armour plating against rockets. very powerful, but very expensive.
missile launcher -> missile era has erased used of artillery. now we launch missile without being in the enemy's line of fire.
Mec. Inf. -> no more huge infantry army. modernism is small professionals soldiers corps with excellent equipment.SPECIAL DCA :
small DCA : machine gun used too counter fighters. useless vs heavy bombers.
DCA : big gun in DCA mount for shooting down heavy bomber. not very accurate, though.
missile DCA : heat seekers missiles give no chance to bombers.
eco-citizen : not implemented yet
Cyborg Inf, and Drone Inf (maybe in english it isn't the word for robotic pilotless engines). -> future war units. beware not destroy the whole world if using this !AIRBORNE :
airplane -> early airplane used for scouting. they have no need of runway (like helicopter).
fighters -> WWII small aircraft can shoot other, fight bomber, and attack lonely ground target. no need of runway. can land on carrier.
small bomber -> cannot fight other airplane, but bombing ground. enough small to make carriers landing. no need of runway.
heavy bomber -> need a runway. High altitude bomber. can not landing on carriers.
nuclear bomber -> same as previous but use nuclear bomb (with manhattan project but before rocketry)
jet fighter -> reactor make old airplanes useless. from this point all aircraft need runway for landing and takeoff .
jet bomber -> can not fit in carriers. (historically design for carry nuclear bomb. I don't know if we can make unit "nuclear bomb", and if it is interesting for gaming).
fighter/bomber -> supersonic airplane with flexible wing geometry for take mission of interception or bombing (like f-14). carrier ok. outclass no-supersonic jet airplanes.
air superiority fighter -> numerous new supports systems makes aircraft more easy to pilot but also rise the cost of those vehicles. not fit in carriers. (f-15, su-27)
interceptor -> smaller and cheaper, the interceptor has been design to fight vs air superiority fighter, but in defense's territory missions. they're shorter range but mass production reduce the cost. (mirage 2000, Mig-25, f-1
. carrier ok.
furtive interceptor -> they are not more powerful than others, but furtive. the problems is this technology is dreadful expensive (anti- detection device need constant repairing...). carrier ok.
furtive bomber -> like interceptor : terrible cost. not fit in carriers.OTHER
helicopter -> powerful anti-armor vehicle, which can carry men directly into city or assault. no need of runway. quite vulnerable of fighters.
furtive heli -> no comment
tank-killer aircraft -> a cheap vehicle design for support ground unit vs MBT and other armored units. You need air control before using this or you'll regret, maybe. This airplane can't fights others and make easy target for all anti-air stuffs.
Awacs ->no need of explanation
