As i have a 360 since Avril 2007 my choice is all indicated
I 'am bored with Civ 4 + its two add-ons becausee mods are take too much time to work and it crash by moments even with BTS patch 3.13 because i have Vista and i cant run anymore Civ 4 on my Vista 64 bits Home Premium
My best remains is Civ 2 in 1990s on PC
It seems that Civ Rev is between Civ 2 and Civ 4 in matter of complexity, so i will appreciate it, dear Civers
