Maybe a Minigames world?

[JT900]

Just a simple world with portals that have names of whichever mini-games could probably be added (splegg, paintball, mob arena, etc).
I think it'd be pretty fun having more than just the worlds we've had for a while now.
We could have tournaments in each mini-game at some point and hopefully get everyone more interactive with each other.

The issues with that is not enough players to run those mini games, as well as mine wars being our current priority; I love your idea though
