This site is built by a ugly perl script that crawls metacritic. I'm not affiliated with them in any way. I just find their layout to be clean and easy to parse, and their game database seems to be very complete. Someday, I hope to discontinue this service when a major game site treats co-op multiplayer as a searchable game feature!
