Since the PS3 just release, my local Family Video store was selling older PS2 games for $7.45. The 3 games I bought are:

Tony Hawk's Underground 2: I own most Tony Hawk games for PS2 and this one is one of the ones that was missing from my collection.

Viewtiful Joe: I already have Viewtiful Joe 2 for GameCube and I wanted the original one as well.

Tekken 4: I already own this game, but I bought it again so I can give it to my nephew since he likes Tekken games too.
