Well unlike gamespot I've probably played every fighting game that was released this past year on most consoles. My top pick would be.....
a tie
Ah yes a tie you may be asking ? The two top games for this year hands down are Guilty Gear XX Slash and King of Fighters XI, I'd probably give Melty Blood Act Cadenza third place with Samurai Shodown Tenka (6) being 4th.
