Wiped on 19 November 2011
Yes. I used to have an OPS2 subscription back in the day and I remember several demos I played and went looking for the full game (I was only 10-13 at the time). Jak 1, Sly Raccoon off the top of my head, and just this month, I bought a 360, and played a demo for Forza 4. Yesterday, my copy of the game arrived.
I even bought my first console because of a demo. I played my older sister's PS1 on a demo disc which had WipEout 3 on it. I then asked for the console for Christmas and soon had Wipeout 3, which is still my favourite game ever made to this day.
