probably shouldn't be writing for this post, but I got immensely interested in the one about AI... I registered to take part in that discussion, only to realise that it had already been closed... So please forgive for letting the steam off here
I am a long time strategy-game player, mostly devoted to Civilization. But now I feel attracted to GalCiv... And this is mainly due to Frogboy's approach to AI, that is, to make it truly challenging. Keep it up, please! Do not listen to all those guys yearning for just more ship designs and fancy races... that is, not too much. New features all like clothes: important, but the way you wear your outfit is the most important thing. In my personal view, AI makes up for 90% percent of a game's attractiveness. There are guys who claim that casual gamers never go beyond "standard" level... But then, do truly casual gamers go for such games which require deep comprehension and extensive reading anyway?
Thanks and good luck
