Bioware's space-RPG was the big winner at last night's Annual Interactive Achievement Awards (part of DICE), scooping gongs for RPG of the year, outstanding achievement in story and, game of the year. While Mass Effect 2 took the coveted game of the year prize, Rockstar's Red Dead Redemption actually won more trophies, netting wins for action game of the year, outstanding character performance, outstanding achievement in game direction, art direction and gameplay engineering. Phew.

God Of War: Ghost Of Sparta took the portable game of the year award, while Angry Birds secured the casual game of the year. Much to our disregard. Heavy Rain and God Of War III were also big winners from the PlayStation 3 exclusive camp.

Hit the jump for the full list.
