So do the numbers indicate the amount of rounds played? If so do we really need this much sub-categories? Just gonna have a bunch of empty slots. If others want all the categories thats cool with me but just a thought maybe limit it in some way.

There are different type of bosses when changing the rounds. Kazumi is usually there when putting in one round, Akuma appears in 2, Devil Kazuya in round 3. But we'll see of anyone manages to see them.

Well I did 1 round/Easy and 2 Round/Medium so far only ever got Akuma but we'll see. (I'll prob just run popular categories)
