Oh yeah, Tetra's Trackers! XD What's the gameplay in that like? It seemed cute.
Tetra or Skullkid... This is actually a pretty tough choice. I love both of those characters! I guess one factor to help break the tie is that there's
something of a chance that Tetra could pop up in Smash 4, since she was in the Brawl files initially. I think we all kind of know that Skullkid will never get into an official Smash game at this point. (
) So PM might be the best chance for him to shine.
And yeah, just the chance to get a proper MM rep seems nice, too. A game that's about loneliness, suffering, despair, and how despite all the horrors in the world, you can still find beauty and happiness (that Anju/Kafei ending always makes me cry, how Link spends an entire 3 days devoting his time to giving them a couple minutes of happiness together, that they won't even remember once he winds back the clock...) It's such a special game, it'd be nice for it to get a nod the same way that WW and OoT have specific reps.
If they did do Skullkid, I think it'd be awesome if they also brought back Great Bay. That's one of my favorite levels, and it'd be nice for him to have a stage.
As always, my opinion might be biased cause I'm a big LoZ fan. : > I think either choice would be awesome for Zelda fans, though, and adding either a pirate or a music-based fighter would be really interesting.
