“Participate in officially tracked Team Death Match, FFA and 1v1 combat arenas that can be watched and bet on live from the web”
I will just say that this feature alone would be extremely hard to accomplish: how would you implement a betting system, how do you prevent exploits, what system will you use to achieve arenas that can be streamed from the web, how are these matches “officially tracked”, how will you accept, hold and pay out payments from users and also do it all legally with the required gambling licences… the list goes on! I would honestly get all of this stuff working and show it off in a video before asking for large sums of money that may not actually result in what you are promising.
