My honest thought on Smash Bros Project

[Koopaul]

That's even too big. Keep it REEAALLY simple for now. No items or ATs or anything just yet. Just four old characters based off of the top Nintendo franchises.

Mario
Link
Samus (no Zero Suit yet)
Pikachu

Two new ones that are really simple to make.

Starfy
Sukapon

And one simple stage.
