The games Xan posted are my 2 games I could only think of.

I am a huge Metal Gear fan but lack of PS3 in my life and rendered me from playing it all the way through. I have done maybe 2 hours of the game and then nothing after that.

Heavy Rain, I got to play the Demo with my friends and we were having fun seeing if we can come up with other outcomes in the 2 character scenarios. I then later found out they rented it without me and played up to the video game boobs part and then they stopped lol.
