I know this game is so old that it's almost a "classic" at this point, but I have to mention that I picked it up for $15 not too long ago and have been having a blast with it.

Amazing graphics and soundtrack. Perfect control and camera angels. One of the few 3D games to get both of those right.

The graphics and control remind me of Ico...you know...just with more killin' and stuff.
