I think there should be a tournement mode depending on when you enter you face the first few people who come in when that player loses the next person in line fights that person if they lose it continues if not the new player takes his place and the loser goes to the back of the line or maybe the map ends then (two maps this can work with Cells Games and you could make one for the Number One Under the Sun Arena or w/e) Basic rules apply to make them easier for ring outs im pretty sure in the maps you can make certain areas instant death x_x so that could do ring outs as for giving up maybe an option or something I dunno you guy can suggest something for that anyway its will make it easier for people to do one on one battles.
