Good stuff...you now own the staple of gaming
Hundreds of titles to pick from...some real gems out there, depending on your style in games.
ICO is amazing, but may not be your thing.
some of the music/rythym games are great (Gitaroo Man, Amplitude, DDR)
Onimusha, DMC, MGS3, FF10, etc. etc.
a ton of games to pick from, enjoy
