Eh... Norfair is just a revamped version of Brinstar, which is very obvious to anyone who's played the original and/or Melee. I'm fine with it though, since it looks fun to play in, as well as random chances I'll spring in a quote from Back Before Midnight. Grab opponent , "I love you man!", then we both die from the huge tidal wave of lava. Fun times.

I never really enjoyed Ness all that much. He was challenging to play as and all, but I never got used to playing as him. I doubt Lucas will be different. PK Freeze kinda reminds me of PK Cross/Flash since you're charging it, but meh who knows how it'll turn out.
I knew Gray Fox was coming! I was hoping he was a secret character, but hell, an Assist Trophy is just as good.
I like the new looks for the Beam Saber and Fire Flower, despite the slit. I can't wait to try out the clock. Or pretty much play this game in general.
There's also a chance Ridley might be an Assist Trophy as well, which I'm more leaning towards. I think there is one last newcomer slot left, so I guess we'll just wait and see if Ridley made it as a playable or not.
