I've played Gulity Gear XX, and GG Isuka. GGXX is much better than isuka due to the story mode... (which Isuka lacks. In fact, Isuka lacks pretty much everything, except it has the beat 'em up mode...)

I also like Last Blade 2, and KoF 98. (Dragonball Z: Budokai 3 got me hooked for quite awhile, too.)
