While I obviously knew that Smash WiiU would be a different game than the 3DS version, i did not expect the gameplay mechanics to be as different as they are. For one the difficulty of the AI has increased significantly; a level 5 character in WiiU Smash is equal in difficulty to a 7 in the 3DS version. Probably the most interesting (and slightly frustrating) change is how the characters handle. Part of this is definitely the use of the Gamecube controller over the gamepad on the 3DS, but I've noticed that my mains just handle different in weird ways. I feel like I've become better with pikachu as a result, however I've been struggling the get the hang of my other main, Zero Suit Samus in Smash WiiU. Funny enough, I'm finding I'm a lot better with certain other characters in Smash WiiU than I am in the 3DS version such as Fox, Falco, and Shulk. It's too soon to tell, but I might have to change my mains up between the 3DS and WiiU versions, although it would make me sad not to main ZSS, I LOVE HER :'(
