Unless I'm mistaken a lot of them worked on Brawl+, a balance mod that came before PM. Then they built from there. I mean, they met through the Smash Community. (Boards, tourneys, etc.)I don't think its neccesary for the sounds. It will be a bigger project for something somewhat medium. Side question: how did the pmbr team meet? I was always curious to know.
This question shouldn't be here tho. I'd private message a PMBR member.
