Obscure Nintendothe prior.
WYR have a bigger emphasis on 3rd parties (with a notable amount of new Sonic characters), or a bigger emphasis on obscure Nintendo series? (StarTropics, Drill Dozer, Mole Mania, e.t.c.)
WYR get a ton of boss characters from Nintendo games as fighters (Marx, Dimentio, etc.) or you have the magical ability to reuse a fighter in Smashdown?
