Hmm...there kinda...like, aren't 5 more Nintendo characters I actually give a **** about at this point. But, if I had to pick:
Can't relate. In fact, I want way more Nintendo characters than 3rd party characters at this point. I mean as of now I still want:
Isaac, Dixie Kong, Captain Toad, Impa, Tingle, Kamek, Ashley, Captain Syrup, Rex, Elma, Andy, Mallo, Karate Joe, Chibi-Robo.
And while I don't personally care about them, Bandana Dee, Waluigi, Porky, and Krystal are all reasonable choices. As are various retro reps like Takamaru, Lip, or Mach Rider. In fact I'm kind of sad we didn't get a retro Nintendo rep this go around, since I think it's always fun to learn a bit more about games/characters I'm not familiar with.
In comparison 3rd parties I really truly want include:
Bomberman, Farmer Pete, Goemon, Sora, Crono, and Tails. Possibly more, but that's what I can think of off the top of my head. I'd be fine with characters like Rayman, Professor Layton, Phoenix Wright, Ryu Hayabusa and whatnot, but they aren't huge wants or anything.
So definitely more 1st party wants on my end. Always interesting to see how vastly people's perspectives differ. I suspect it is partly due to how I view Smash as well, since I definitely prefer to see it/think of it as a Nintendo crossover first and foremost and as such I'm not as enthused about the idea of 3rd parties just based on how epic they are as a character/franchise (note for example I didn't include anything from Monster Rancher despite it being my avatar). I'd rather 3rd parties remain a smaller part of the game and for them to be focused more on characters with close ties to Nintendo.
Note that I realize this is not necessarily how it works, but that still informs my wants.
Anyway, I suppose I could try and actually make a top 5 like everyone else was doing so here goes:
1st party pass:
1. Isaac
2. Dixie Kong
3. Captain Syrup
4. Impa or Tingle or even just more LoZ rep
5. Karate Joe
Though in reality, my 1st party wanted characters are all pretty equal after Captain Syrup.
