I'm perfectly fine with 3rd-Party characters being brought in, as long as they actually are a prominent figure in Nintendo. 'cause think, some other 3rd party characters that'd make sense would be Bomberman or Pac-Man or Mega Man. All those guys have had a huge career on Nintendo systems, so it's not like sticking Master Chief or something obscure like that, in. Plus, the other new characters seem good too, since I absolutely wanted Meta-Knight in there, right from the start. (And as for Pit, they spruced him up a bit so it's all good.)
Most important of all however, people, a moment of brilliance dawned on me: 3rd party character support means we might see Geno or Mallow perhaps, in the next Smash Bros.
