1) I've got nothing against games set up with Hex-based maps. I don't believe it will increase GreatTurn's numbers much.
Want to play them? Go right ahead! I won't be joining you, however, and neither will a large number of players.
Take a look at the number of Hex tilesets out there http://freeciv.wikia.com/wiki/Tilesets
... definitely the minority.
Davide has made it clear that he wants to grow GreatTurn by significant numbers. Doing so will require bringing in many casual Freeciv players, most of which will find playing on a Hex map totally foreign to them. I agree it's just a 2-D cartographical representation of a randomly generated geological surface, with a super-imposed grid that determines movement (rectangular, isometric, hex, etc...). However, such a big variation in the normally-accepted way of playing will off-put many players and consequently turn them OFF from GreatTurn (which runs counter to what Davide is trying to accomplish).
2) GT games should be configured by Consensus
You can't make me believe that 5 people voting for a Hex-based game (not even unanimously, but 3 out of 5!) represents the will of the majority of players, when 25 people sign up. Therein lies the problem: A minority of players should not adversely affect the enjoyability of a game by introducing obscure changes. Instead, either have players join a pre-configured server where all settings are known up-front... or, allow settings to be voted on AFTER all players have registered (but before the game begins). Quorum guarantees that a majority of views are taken into account, and the majority of players agree with whatever settings are changed.
3) All settings should be clearly
indicated on a given GT server
Should there be dedicated Hex-based games for GT? Yes, you bet! But make sure that it's advertised & known well in advance for anyone wanting to joing that server. That way, "hex" players have a chance to play their games with people who know what their getting into in advance. No nasty surprises after the fact. Here I think there could be some improvement because I did take the time to read about the proposed changes for GT01. I noticed increased movement, increased city-size, etc... but never did I see the fact that it was going to be Hex-based. Perhaps Davide should have made that a bit clearer.
That's it for now. Rant is over
P.S. Davide: I'm very grateful for the hard work you've been doing so far getting this off the ground. Keep up the good work!
