OK, I DEFINITELY agree with you, Spatula, that the strongest focus should be in making the peaceful game MORE attractive but, at the same time, there should also be attention paid to making war more.....realistic, which I feel would also be good for gameplay. By realism I mean making war weariness dependant on more disperate factors-such as victory/defeat, government/religion/culture being fought and distance from home! Also, giving units an improved economic and population cost AND limiting the ability of said units to fight wherever and WHENEVER they want. I guess what I am saying is that I don't want combat to be RESTRICTED, merely have it tweaked so that the strategic and tactical elements of war are more engaging (hope that makes sense?)
In parallel, I would like to see culture revamped and improved, along with the economics, population growth and research models. Lastly, but most importantly diplomacy and international standing (especially in the modern age) should be beefed up quite considerably!!
Last of all, related to your question about victory conditions, I had this idea of the game ending at a random point between say 2100 and 2500-the point is that you don't know exactly WHEN the game will end within that time frame! When the game ends, though, each of the seperate victory conditions (which are currently active) are checked to see who won, and the player who wins the most victory conditions is the overall winner!
