Has a Quick Look ever made you to buy the game it was featuring?

Nope

" Seeing the opening minutes of Batman Arkham Asylum completely sold me on that game. "

I was going to say no, but I might be sold on Champions, after that Quick Look.  I was kind of losing faith in that game until I got to actually see what it had to offer.

Actually, yes. It has influenced me to buy Battlefield 1943 when it comes out for the PC. And if I ever buy Champions Online, it will be because of the Quick Look.

I barely knew anything about Shadow Complex before the Quicklook. Just watching that sold me. I got it as soon as it went up the morning of launch.

Not yet

Battlefield '43.

Batman AA, would not have bought it otherwise.

I bought UFC: Undisputed 2009 because of the Quick Look. The reviews have more of an impact with me, the last decision I made was getting Infamous after reading Brad's review, which I was really happy with.

It's encouraged me, but I've never straight-out bought a game because of a quick look.
