165193. Most of what I usually play are PC-based. I recommend the whole Civilization series, so long as it's not the one published by Activision. On the subject of that series, Civilization Revolution (console version of the series) is good, but I find it too easy to win it, and too quick for me. I love long games of Civilization. Alpha Centauri came from Sid Meier, too, for PC, between Civ II and Civ III. Black & White is a good game, as is it's sequel (as long as we're willing to venture into the RtS genre). Then there's the stalwarts of the RtS genre - Startcraft, Warcraft II, Warcraft III, Age of Empires, AoE2. Empire Earth I & II were okay games, but III sucked, in my opinion. LotR: The Battle for Middle Earth was fun (I can't remember whether it was I or II that I had, though). I'll be right back after I go check my games case.
EDIT - Here's a couple more:
1503 A.D. - The New World
Command & Conquer - Generals (never played it, though - was too interested in LotR: The Battle for Middle Earth and Black & White 2 from the EA strategy box I got it in back in 2006).
