Hey, Its kind of hard to describe what I'm thinking but I'll do the best I can.

Starts off choosing a mod type that you like (aikido, any shu mods, weaponed mods) and it takes you to a lobby of a few different servers that have that mod type. So if you chose the aikido based mod, it would have rooms with aikido matches, greykido, aikidobigdojo. You get the point.

When you enter one room it takes you to a "world" for lack of a better word, where you're mainly focused on the match you chose, but you could also see other matches happening. Say if you chose the aikido room and chose greykido.tbm match 1. It would take you to that match like normal, but in the background you could see what would be aikido.tbm match 2 or aikidobigdojo.tbm match 1.

Sorry If I didn't explain thoroughly enough, it's kind of hard to put into words for me.

If so, would just technically be multiclienting causing some server issues. Pretty that's why you dont see many games with this. I cant even think of one.

Give a game with said system, provide a hypothesis of how it'll work.
