Unfortunately these do not lend them selves to multiplayer server - they usually need to be manually reset, and are at the most 2 player at a time, plus they can only be played once through ( maybe twice) before they get boring.

I think its a good fun idea, but just not feasible. If you want to try some of the ready available ones, drop the minecraft server on your local pc and install the ready made map. they are fun. I recommend - "its better together" me and Hannah had a fun time doing that one. its 2 player.

If any one can think a way around the inherent limitation, I am all for it.
