Don't forget Little Mac is legendary. Punch out was THE game when I was a kid. Everyone loved it. Kid Icarus? Yeah it was cool but it wasn't as user friendly. Getting pwned by eggplants isn't everyones idea of fun.
Btw do you guys think Pit would be as well known today without Brawl? To be honest I thought he was called Kid Icarus until recently. I still don't know/care why he's called pit.
Also if possible I think you should remove pit and olimar from the list since they are very limited and most people probably don't even know who they are.
Add Luigi since he's almost always been a part of anything Mario does. I think he deserves equal standing for his efforts.
Add little mac for being legendary.
