Okay, so, mage games. Obviously the main attraction is all the magery going on.
But, what about the rest of the setup? Would being a band of roving adventurers be different from being a squad of royally-directed agents? What if they were royalty, or servants of an evil overlord?
I guess what I'm asking is, what's the best context for being a Fucking WizardTM in?
I've been fiddling with a perma-death mage RTD myself. The basic idea is that an ancient labyrinth built by a powerful Dark Wizard has been discovered in a dwarven kingdom. This kingdom has forbade the practice of magic for hundreds of years, but there is a curse on the entrance to the labyrinth that prevents any non-magical being from entering. The cruel and despotic dwarf king wants the no-doubt tremendous riches inside, and so grudgingly sends out a call for mages to come and test their luck. Thus, they come from all over, are placed into impromptu parties, and are sent in.
Think Magicka with a group of four friends. The party would need a wide range of magic to succeed, and death would come quickly and brutally. Thankfully, more can be sent in as needed.
