A few months ago, I decided to try Civ V: Complete. I fell in love.
Later, I went searching for a similar drug, a space empire building flavored one. After hours upon hours of googling and youtubing, I decided to give MoO 2 a try, just to check what the fuss was about. I fell in damned love again, like a happy junkie in the sky.
Then, I tried GalCiv 2: Ultimate. It didn't click. I finished an influence victory being Torian, it was nice, but not that much.
Then, I tried Space Empires IV, V, Endless Space and Distant Worlds. None clicked. Each one with its own faults/roughnesses pushing me away to reality.
THEN, I tried GalCiv 1: Ultimate. I fell in love again, happy junkie, et cetera. Very different from MoO2, but I might say it's just as good.
So, right now: anxiously waiting for GalCiv 3 and Civ: Beyond Earth.
