Dumb question but where is the direct streamed? YouTube? Twitch? A Nintendo site? Never actually sat down and watched one live.
Don't really care what newcomers we get (as long as it isn't Steve or Dova. No offense to supporters intended, just not characters I want in Smash personally), but I would really like some sort of Great Cave Offensive type mode similar to SSE in gameplay. SM4SH was kinda lacking in single player content for me, and I'd like something like that with maybe a character-specific cutscene at the end.
And I think it'd be great for said mode to be the method for unlocks. Maybe randomize the layout and enemy placements each time. Have chests with music, custom moves, mii costumes, coins, trophies, etc. Have other characters show up for fights, maybe make a couple non-character bosses. Do certain things in the mode to unlock characters who you fight after the ending cutscene, or just have them in secret rooms/areas.
Also I would love to have Smash Run revealed. I love Kirby's Air Ride City Trial mode it's based on, and I never got the 3DS version to experience it
