I enjoyed the first game enough, but got bored half-way through the second one. Still finished it, but I think there is something about the way Bioware does its level design that just fundamentally disagrees with me. I felt it in the Star Wars RPS, I felt it in Mass Effect. As a result of those lack-lustre experiences [EDIT: and, of course, Origin], I had little interest in ME3, though it is interesting to see how they decided to wrap up all those decisions we agonised over in the previous games (read: apparently not very well)
