You probably all know the drill from IMDB and the like and we all have seen the "top ? [insert genre] films/bands/games" lists and maybe even made a few of our own. Specifics would have to be hammered out- automated (probably quite difficult), voting (and if so what are the requirements- staff, confirmed, vetted, anyone), ranking order not to mention the big question of "Now we are 5000 releases deep how are we going to generate that much data to make it appear worthwhile in a short space of time", whether we have a few wildcards in there to stop it being a validate my taste type list and I am sure it could go on. Concerning the matter of quality I have to assume there will be jokes, bad posts and beyond but I reckon the net effect would be positive. My line of thought being that it would be more along the lines of hoping for the odd game I never heard of rather than trying to be a definitive list.
