meh, ME2 was one of the best games I've played this gen, but its seems like it's forgetting it RPG elements, and ME3 looks to be much more action oriented then what bioware is ckaiming it to be. I think the reason why FFXIII sold more was because of brand name, the FF franchise is considered the king of RPG's, even the non-rpg players atleast know what it is.
as for FFXIII, I enjoyed it, not one of my favs, but it was enjoyable. my only complaints was the linear paths, you didn't get to explore until chp 11(out of 13) and you really customize you party until chp 9, and my most hated was the the leader dies the battles over. I really enjoyed FFXIII's battle system,I think it the best of the mainstream FF titles. and what's with the people saying there were no side quests? there was a fair amount of quest(well missions) to be had.
I think FFXIII hate is a little undeserved(imo) but I do get where people anger comes from, S-E really threw the usual FF formula out the window, but like one poster said in another thread awhile back "the people who hated FFXIII will probably be the ones who buy FFXIII-2 and hate on that"
