bioshock and mass effect 1 and 2. they made me say wow in terms of story and such.

Uncharted 2 after I beat it, I said 'Wow, what a total waste of quality gaming time.'

The Witcher 2. The little I have played of it is ****ing SICK. I wanted to stop playing it because my PC can't max it out and I don't want to ruin the rest without seeing the effort CDPR has put behind it.

World of Warcraft , what else :D

MH3 like "WOW this game is gonna soak a great deal of my down time" then a bit later it was "WOW, the camera is gonna send me on a homocidal rampage soon" but mostly the first one :P.

Gears 3 is the best looking game of this generation without a doubt.

L.A. Noire
