hey there people,
this is my first time on the boards, so i don't know if this question's been discussed already or not, but I was wondering if there was anyone out there who had played space empires iv and galactic civilizations...i'm on a rather limited budget, and i don't really have time to get into two big 4x games at once, so i was looking for some suggestions as to which game is a better buy...mostly i'm looking for gameplay depth
