I am playing Rayman - Raving Rabbits. Got my niece to watch me play it as well It actually kept her entertained quite nicely and she is only 2 years old. She even had a go at it.
Well, I had all these new releases like Assassin's Creed, Saints Row, etc. planned for this past weekend... and got hooked on Fallout 3... so I didn't touch any of those.
Playing Skyrim at the moment. Although I would love to give some older titles a go that wouldn't play on my old system. By older I mean the last year or so where my old PC just couldn't keep up anymore. So got lotsa catching up to do. But I don't think I can stop playing Skyrim until I take an arrow to the knee
Basically I'm doing a combination of playing Fallout 3 and crashing to desktop, and repeat.
While the game is unstable / buggy as hell, I still find the game worth the trouble. I hope Bethesda's newer games (i.e. Skyrim) has less issues.
Over the last couple of months I finished Gears of War 3, Uncharted 3, Deus Ex Human Revolution, Batman Arkham City and Assassin's Creed revelations. At this point nothing in my list of "unplayed" games even begins to interest me.
