.HACK is a tad too weeaboo for me, Gungrave is great fun, but gets old relatively fast. Jak & Daxter is immense (fuck the sequels), Dragon Ball Z Budokai 3 is one of the best fighters on the system that's great even if you're not even into the show or fighters in general, Devil May Cry, Timesplitters Future Perfect, Wipeout Fusion (though WO3 Special Edition is the best game in the series), Psychonauts, Ico, Okami, most pf the Tony Hawks games, plus all of the fucking sweet retro compilations too, Not to mention that you have the entire PSone ibrary too, and I could go on for years about that since I'm a PSone collector hahaha
