You know, Civ4 is waaayyyyyyy too time consuming, and so I don't really care for the series anymore. Yes, I know there will be a lot of "blah" coming at me, but here are all the games on Gamerankings that are higher than Civ4 (not in order).

And it's missing a buch of old games (e.g., TIE Fighter, X-COM, StarCraft) plus things like Metal Gear Solid 3, Final Fantasy VII, Final Fantasy X, Final Fantasy XII, Metroid Prime 2 and 3, Virtua Fighter 4, Madden NFL 2004, Mario Kart DS, Rome: Total War, etc.
Honestly, I have to wonder why you guys are not playing one of the aforementioned games instead. I stated my opinion; I can't understand why anybody would get into Civ4 unless they forced themselves. And I enjoyed other games previously; I remember playing Soul Calibur II at my cousins' house and I loved it (almost more than Smash Bros., and at the time SCII actually was above Melee by 2% at GR). Mario Galaxy was just no-war, no-maintenance fun, and Metroid Prime 3 really filled in the dark void that Mario Galaxy missed for me. And Twilight Princess had awesome gameplay and graphics, though the ending was ultra-childish for a teen rated game. Civ4, on the other hand, well, now I'm deciding between StarCraft and Civ4 to play.
