After playing Moo3 for an hour or two, my first impression was, confuzzled!!!!!
After playing it for many hours, my impression was of banging my head repeatedly into a wall. Maybe after playing for many many hours it will get better, i don't know.
After playing GalCiv for two hours, my first impression is *insert giant sucking noise here* I barely even noticed the two hours passing, it seemed more like a half hour. Maybe after a few more hours i'l find it's lack of depth disturbing or something, but so far all is good :)
