That sounds like an interesting scenario. I think I got a few good places that are really good places for rings, one being the bases on blood gulch nice and close through a few skulls for the "Boxing Gloves" and that would be a fun game. Another base that might be nice is the base on Icefeilds, a bit larger then blood gulch bases so a bit more room to shuffle around in, as well you got that center pillar that will make for all kinds of crazy fun ideas. I really like the Icefeilds base because it best fits the image of the Battle Dome From the Mad Max trilogy, you know, two men enter, one man leaves, and then the other one leaves when they respawn. And to make thins really fun use the top of the base on Infinity, a bit of boxing and Sumo wrestling, plus it be fun if the soon to be winner stepped to far to the left. I mean there are so many arenas you could discover all with there own unique advantages and disadvantage for the fighters. Unfortunatly the game requires a lot of structure that it couldn't really be open to the public, but would have to be regulated by being between friends and/or fellow clan members, yet still a fine idea for a boring afternoon i would say.
