Umm...I'm not sure, but I think he means that you and your friends on your own take on your own monsters, like fight pits without other people and without the waiting and killing the other people, but I'm not sure, so don't quote me on it. Even more on-topic: Small addition, you would be fighting against other things that you might actually face in the arena...Like you would set rules and they would actually be human, like people you might face in the arena, say, they use ancients, so you would learn how to fight them, and in time, be able to beat them. Suggestion asside, well done! Good idea, support!
