FarCry: Though a timelessly epic game, it's still got a lot of annoying bugs and issues, such as being seen by enemies when sitting still behind a wall, gunshot sound loops, and enemies watching whenever you move no matter how far away or how slow and silent.
Dark Messiah: Same as FarCry. Though an awesome game, it's got issues with bugs. But what else would you expect from ubisoft?
Beyond Good & Evil: I tried to start playing this but the intro movie speed at 3x normal speed. Till I can find a fix for that I'm not really gonna try it out yet.
IL-2 Sturmovik 1946: Apparently one of the best WWII flight sims around. I guess I'll give it a try.
