Idea for Minecraft Xbox 360 version Hunger Games

I have a idea for the hunger games in the Xbox version of Minecraft, You build or find a huge cave and put a starting point some were. Then you make people fight for survival against monsters and if they go deep enough in the cave the other players. The last person surviving then has to find their way back to the starting point with out dieing. If they make it back before they die they win a prize. Me and my friends are working on building a HUGE cave on one of my worlds. Then we are going to test it. Would anyone want to be a test subject?, If so send me a MSG and I will tell you when the cave is ready for testing.

Wait until the minecraft updates
