I'm looking for a diverse selection of characters. I have no need for the story or for the characters (or even the graphics) to match. More and more I'm thinking 48 is probably the correct number of characters for me

There isn't going to be anyone using the mugen I make for competitive play, so the balancing is going to be done around the ai vs ai matches (most players are 8-13 and are just going to mash hard punch anyways).

The control scheme also needs to be accessible. I don't mind having some input required from the players, however one of the biggest problems I've had over the years in fighting games is players that don't basically dedicate some serious amount of time to the games being completely locked out of being able to play them effectively. I've literally won matches in games before standing still and pressing jab when the opponent got close because the inputs for special moves were so difficult my opponents options were A: button mash B: attempt them and effectively do nothing at all while playing. Smash Bros is a good game in my opinion basically for its controls alone due to this, though far from the one I'd put at the top of my own list.
