Okay, I can easily imagine people saying Metal Gear Solid 4 here, due to the hour-length cutscenes.
Civilization IV, well, it's definetely 9.4/10 material once you get past the crazy lag at the end of a game. With that, though, it's at least a full point lower.
I understand the whole opinion thing. My younger brother, for example, hates turn-based games. So for him, Advance Wars, Tactics Ogre, Final Fantasy Tactics, Civilization, and X-COM are piles of garbage.
Admittedly, Gamespy had some nice picks in their top 25 most overrated list. Super Mario Sunshine @ #24, Morrowind (noooooo!!!) at #21, Impossible Creatures at #20, Halo at #10, Final Fantasy VII at #7, Quake II at #5, Metal Gear Solid 2 @ #2, and #1 was...
BLACK & WHITE!!!
Net Tens' #1 was GTA: San Andreas, and the others were, from #2-#10, Tomb Raider, Super Mario 64, Gran Turismo 4, DOOM 3, Metal Gear Solid 2, Jade Empire, Halo, Duke Nukem 3D, and Half-Life 2. That's a load of shooters there!
Yet another one had the Halo series at the top, followed by Final Fantasy VII. He also had Animal Crossing, Harvest Moon, and The Sims (he probably doesn't like that genre) along with Mario Kart 64 and GoldenEye 007 (stating that the former is nothing special nowadays and that the latter was killed by Perfect Dark).
Okay, don't get mad at me for posting this. I think I can draw the conclusion that the Halo series and Final Fantasy VII are quite popular choices.
