My thoughts on the DLC:
Miiverse – Do you have to play online for it to work? It's just plain when I play offline.
Dreamland – Lazy AF. They couldn't redo the stage, and just ported that low poly mess?
Suzuka Castle – Prettier in screenshots, not too much to play in.
Mii Costumes – I love Zero and Megaman.exe!
Lucas – Eh...he really got overshadowed in this release. I like Ness a lot more but it's so satisfying to kill someone with his up smash.
Roy – He is so much fun to play as! So freaking powerful. I love catching people in the neutral b explosion. You can kill someone at 0% with a fully charged hit. Such a great addition.
Ryu –*He's so difficult to use

I try to do the Street Fighter motions but they're hard to pull off with the Wii U gamepad. I always end up facing the wrong way. He seems really OP at the moment, but I love it!
