Roundtable reviews. Take 3-5 of the top (trusted, knowledgeable, & well-written) members here and have them provide discussions on new game releases - each provide short paragraphs to questions like "how are the online options and gameplay". Group the answers together for a review representing the different viewpoints. Dont bother with scores, let the words do the talking. You may even want to have a group of review specialists for the different genres like FPS, sports, RPG's, etc.
The traffic this site gets should get some review copies of games to the reviewers no problem. I like to read reviews when Im on the fence about the game, dont care much about scores but different viewpoints from people who's opinions I value. I think this would be helpful for all. JMHO.
