Imma hold a tourney with all stages on.
I'm not fvcking kidding either.
Actually I think that's a good idea, but only if you put on non-broken items too. This game is a party game, and should be treated as such. It is
not a highly competitive, ingenuitive fighting game. It was made with the exact intent for it not to be, and unlike melee, there are not enough glitches or easter eggs to turn it into one.
As for item-less play:
I'm fine with Neutrals as they are now.
Stages I think should be CP:
Luigi's Mansion
Pirate Ship
Norfair
Frigate Orpheon
Halberd
Pokemon Stadium 2
Castle Siege
Distant Planet
Hanenbow
Not sure whether to ban or CP:
Bridge of Eldin
Port Town
Summit
Pictochat
Shadow Moses Island
The rest should be banned.
Oh yeah, I didn't include the returning Melee stages, some of those should obviously be CP.
