i'm 4 pages late, so i'll just generally reply to what little things i've barely read.
no third party should have more than one rep, nvm more than one rep from the same franchise. their rep should be versatile, from the 80's and appeal on both the hardcore and casual side of gaming. pac-man falls into the categories, but personally i feel he should be in a mario party game before a smash. there i said it it's out on the table. i'd rather see klonoa or mr. driller/dig dug with some Pac-Man based move or... i dunno a hat. we already have a great interpretation of an old school character in game and watch. it's debateable whether on anyone's side their needs to be another. but if there were another, why not another team style setup? sure it would make ice climbers less unique if there was another team, but the case could be made that pac-man's inclusion would diminish game and watch's.
please read could be made. we could argue but what's the point. then again thats what people do mostly on this thread anyway
