Again, I'm against any settings that minimize the benefits of alliances.
In this situation (GT09), having a game where there can be no allied victory means that any alliances will be temporary at best. Ultimately, these marriages of convenience will only last as long as necessary with the ultimate result being that the alliance will *have* to be broken, one way or another.
So, instituting measures to minimize the benefits of alliances only encourages players to adopt isolationist policies, instead of cooperating to achieve mutual goals. Part of the fun of playing online, in a multiplayer environment, is the teamwork aspect. Putting restrictions that minimize the benefits, especially in a game that won't allow an allied victory, encourages a lack of teamwork in my opinion. Yes there are still ways to cooperate with others, but it's a lot less fun and frankly newer players need to learn the lessons of proper teamwork and alliance cooperation. Otherwise we may as well be playing against the AI on expert setting. What's the fun in that?
Yes more experienced players will leverage the benefits to the max. But I put this onto you: perhaps veteran players should consider allying with lesser experienced players to teach them a thing or two. I'm glad that Monami taught me a thing or two during my first game when we allied together, and I'm more than happy to ally with lesser experienced players in this game (provided that it fits with my future strategic objectives, of course).
