Add another one for GTAIV.
San Andreas had way more diversity to it (from characters to locations). Even though I finished it, it was not the game everyone made it seem to be. Most of all, it wasn't fun (many blogs on cag point that out with Saints Row 2 being the better alternative).
Maybe I would have felt different if I waited and got it real cheap last month?
I think I'll replay it just to get hyped for the dlc next month. I got the 360 version primarily for this reason, so I might as well.

PixelJunk Eden (abstract platformer, ay?)
Patapon (gets real frustrating..less intuitive)
Mario Kart Wii (might have to replay it, but MKDS was superior on all fronts - 'rubberband' ai is at its worst here)
