Over at the Dee-Nee forums (dedicated to RBI baseball which is one of the greatest NES games) a guy is putting on a NES bracket/tourney. about 30 or so guys listed thier top 30 favorite NES games, then he took all the votes(within a points scale) and created the brackets. from there we each vote on the match-ups. Every 3 days the results are tallied for a few match-ups then we move on. Since we are all RBI fanatics, RBI was excluded from the voting to make it fair. personally i think RBI still could have been beaten in this tourney anyways.
heres a linky to the results thread.
Updated NES Bracket Thread The most current results can be found on page 2 They open in a MS excel file. If you look in the anything goes forums on the 1st few pages you'll find the discussions there for all the NES game match-ups.
So far a few upsets as Ice hockey took out mega man. Stalwarts like Zelda/Tecmo Super Bowl/Mike tysons punch out/Double Dragon(i hate that game and it beat Kid icarus)/Castlevania/Final fantasy.
Currently Metroid is taking on Bionic Command/Dragon warrior is taking on tetris.
