FF XIII - 90 Some probs with linearity and lack of exploration I hear. JRPG's not quite so popular.
ME2 - 92 RPG purists voting it down as a TPS, some bugs inevitable w/ BW and new engine.
I think we can assume Square produced a beautiful bug-free product but Bioware are innovating on the conversation system, have fixed tec. issues and quests. Plus wrpgs are it with the western press now. Even the MS haters won't risk cred. by giving this 7s. FF might struggle staying AAA if long time fans don't like the comparison with prev. FF. ME2 has only one game to improve on.
