Wario Ware- "This stage regularly hands the victory to one player or the other through pure randomness. " How is this any different than Pictochat. The animations/hazards that come up for pictochat appear in a random order, yet you know all the types of animations. The games on Wario Ware appear in a random order, but we know all the games that are played. We all hear we need to learn the stages, so if we learned the games and won all the time it wouldn't be so random I guess.
If you believe Wario Ware randomly awards wins because of how powerful the punishments are when you lose (put yourself in bad position when you lost the game), then the same can be said for Port Town's cars, Jungle Japes Alligator, Green Greens bombs, Distant planet's man eating monster, Pirate Ship's bombs/spring/and ship itself, rainbow cruise's movement into blast zones, norfair and brinstar's lava, Frigate's rotations, Yoshi's Island Brawls falling cloud, Yoshi Island Melee's disappearing blocks, everywhere's walk off ledges.
I can't believe you guys would ban stages like Wario Ware and Corneria. The lack of stages in this list is certainly hindering the potential of competitive play in this game.
