Smash was my Wii U game of 2014 (surpassing Bayo 2 for me), and I'm not even a huge Smash fan. I played and loved Melee and Brawl, but I never got too in depth with those. Smash 4 is the only game in the series I feel 100% invested in and I want to unlock everything there is.
I don't think I could've asked for anything more. Maybe some more stages, but those can be added in DLC eventually. I didn't really want a story mode since SSE felt like a chore to play after a while. Overall, I'm very happy with the game and it's quickly become one of my favorite games for the console.
