Hm, Nice idea, but what if it was like a sealed off Dlayo Pit maze, where you couldn't jump out of it, but people could use magic to send you back to the start of the labyrinth.  It might be nice if it was like Crete, where there was a labyrinth that ended up with an immensely tough enemy.

Entevir, the control-point idea seems great, and it is feasible, not dreamy, you would just need a "commander" to decide who wins, and a neutral player at each control point to report to the "commander" which team controls the point when the point is captured.  A commander idea would also work well for prizes, perhaps the best players from each team would be deemed "captains", and they would guard the points, and whichever captains are left alive at the end get some special prize... Well, good idea Entevir

One thought I had was if there was a "flag" or two for the attacking team to capture, this would add some worth to the battle, but, it would have some drawbacks such as;
--What would happen if a defender or non-participant took the flag
   A solution to this might be to have a "flag-guard" that will not accept challenges, but will walk around the BD, with the flag, and if  a member of the opposing team walks up to him/her, the flag-guard must trade the flag to the opposing player
--Should an attacker with a "flag" be killed while returning to his start position be killed, the flag would not be dropped, and would be with him in the Death Realm
   A solution to this would be while the opponent has a bit more than 0 life, and is sitting, he/she will drop the flag, and be able to return to his/her base.
With these in mind, once we could resolve these problems, a "capture-the-flag" theme might make it more fun.
(Maybe sometime in the future the dev's and GM's could organize something like this)
