IF I ever organize anything:
Virtua Fighter:
Ring size is 42m
NO Knocking your opponent out of the ring
NO cheap-ass moves

Skulltag:
Duel Mode using the Duel mod I'm developing (BFG9000, BFG10K, and Railgun replaced with weaker weapons for more balance, and more balanced maps)
Attacking an AFK/chatting opponent will result in DQ.

Goldeneye:
Automatic weapons only
Stock maps only
10 kills
You may not attack players while they're away.

Halo, since it's balanced, there's no need to change much.

Any other fighting game (not MVC2):
NO FUCKING SLIDE KICKS!


On topic, I prefer SSB on N64; NO Final/Pity Smashes, No tiers, and without GS, you can't fight in Final Destination.
