Capcom vs SNK 2, and the SF Anniversary collection (for SF Alpha 3 and SF3:TS) for me. KoF 2002 was another favorite of mine as well.

Was Garou MotW ever released for the PS2?

AC without question. You'll get hours of awesome exploration, vertigo inducing chases, and, of course, assassinations!

Hmm, makes me want to go back to AC 1 and finish off those Templars... :)
