Jet Set Radio, I loved that game. Dead Or Alive is a game that's been forgotten in recent years, it hasn't had an game out since 2005 and although it's got a 3DS version coming out it's been pushed aside in favour of Ninja Gaiden really. Oh and:
I loved BOF3 & 4 but apart from a PSP port of 3 a few years back there's been no new games for ages.
