+1 I wouldn't mind something like this. I find it hard to find a lot of Project M online action.

I'm not a fan of Lylat but I don't see why it can't be a starter. Sure the stage ledges move but It's not like that's a problem for the "viable" tourny characters mainly just the low tier "unviable" ones. Falco and Marth seem to be the only characters I can think of that could have a problem with the tilting of the edges. Other than that the other viable characters do fine. Also I'm assuming that viable is B tier and higher. Even the unviable characters seem fine except for Ness, Lucas, Mario, Link(of course),Zelda, Ganon, Ike, and Wolf if he has to resort to UpB for recovery. so that's only 10 of 36 character that could have a problem with the stage but like I said most of those are "unviable" so I'm not sure how much that matters.

Major hackers in general. People who actually know how to go into a system and decipher its binary codes and then change them.
