I know people have already talked about this but I haven't seen any topics on it.
So would you guys like to have unlockable characters like Smash Bros.? It could definitely add replay value and challenges regarding how the criteria is to unlock characters. However, if someone wants to main one of those unlockable characters then they're required to obviously unlock them before trying to main them. So I guess it could go either way.
As long as they are not too easy to unlock. I am looking at you Subspace Emissary. Other than that, it will be fun to unlock characters. Speaking of unlockables, perhaps we can do the same for the Stages.
