disliker of the mary sue
acully wellwisher i played 3 on 3 once i even played 9 -1 when i was 1.
I suppose you've never played a 14 person free for all then. and, i don't think Yu-Gi-Oh has rules for more than 1 vs 1 does it?
i think that might be a problem since people then have to customize rules with special interest to some cards. (magic has some cards that only work in multiplayer believe it or not.)
Oh, there....are probably another 15 versions of magic (that are beginning to surface now) which makes new formats of magic great. I always felt that yu-gi-oh had that as a nissue because it would be impossible to cover for every card when remaking rules for special yu-gi-oh formats.
