I'm going to receive hate for this but The Fighter Passes of Smash. I don't dislike that they have them, but I dislike that they focused on adding new random characters when they could have added more features to the game instead. Features I'd love for the game to have:
Amiibo online battles. You have your lineup, I have mine, we let them battle it out while we eat smoked guoda cheese and drink a fine 2017 blackberry sweet wine. Throw in a leaderboard while your at it.
Story focused single player with linear plotpoints that build up to epic CGI moments.
Smash App where you can challenge friends, set up times to fight, get live updates on Smash leaderboard changes and events, and talk trash with the internet.
I like new characters, but that's all they seem to be focusing on and that is the least of my concerns when it comes to Smash. They have a fantastic lineup already. We need new features!
I gotta disagree with that... Not that I wouldn't like most of those features (except the app, which I can't see myself using), characters are the #1 thing I want in a Smash game. And even if you personally have different preferences, do you think these new features would generate as much buzz and money as new characters?
Also, they did have an amiibo tournament. Would be cool if they turned that into a regular thing. Although you can use them in arena battles. Dunno if you could make one specifically amiibo only.
I'd like to think people would want to throw more money at DLC that includes fun new ways to play and enjoy the game rather than just new skins on either identical or extremely similar characters, but I'd probably be wrong.
