Wow. I missed a lot. Guess the four letter word I'm thinking!
As for the setting, if it's still up in the air here's how I view it.
Enrollment/Gladiator Identities:
Anyone can sign up to be a gladiator, there are no real restrictions preventing people, assuming they can survive, and succeed in the demonstration of their abilities. So as not to deter people from joining, aliases are accepted. Contact information must be taken however, much like a job application, and photos will be taken, both directly and a profile. Information is tracked on these individuals, but only what they freely offer, or is relevant to the wRHG, such as battles, clans, and known gladiator associates. These profiles are freely accessible to the public.
Finding Each Other:
It's really just a matter of matching up the face and asking around. For the sake of stealth, there are no real trackers.
Contracts:
Because anyone can join, people have different contracts. Although someone may be new, a more threatening match will pay more, but all stars are compensated well regardless. With the medical equipment being so advanced, it is also extremely expensive to use. Not everyone is revived. If someone costs more than their worth, this will not be offered them. Sometimes a death even adds to the legacy of a villain, so that's a card the corporation would be happy to play. Additionally, time contracts may be issued, such as you must have x battles in x time to retain something, such as the revive, or housing, if they offer that.
Battle Recordings:
So, in my mind, there are three main types of battles.
1: Arena
No question, this will be recorded with state of the art equipment. Kinda sorta implied, and I think we can all agree on that.
2: Premeditated Challenge (away from arena):
Gladiators will be given small, subtle cameras to capture the events leading up to, and of a battle. There are also scattered cameras across battle 'hotspots', such as forests. If necessary, a cameraman can tag along.
3: Spur of the Moment:
So these would be the hardest to record because there's no real planning around them. For the most part however, the wRHG just has to buy the footage off the cameras around the event. They are well known to pay well for cell phone footage of their battling gladiators.
The RHG:
It's founded in another nation, and practically is a nation in it of itself. Their arenas are like foreign soil, so what happens there, like death, cannot be acted on by local law enforcement. Although they should be safe, people really enter at their own risk. Spectators have died before. The RHG employs people for all sorts of jobs, including security, camera crew, various TV positions, enforcers, researchers, scientists, doctors and so on. The main difference between RHG and wRHG is the latter shows more the lives of the gladiators, what leads up to, and what follows the battles. RHG basically just showcases the fights. RHG and wRHG both handle their own affairs, and although they're the same company in the end, they are very hands off for each other. Their shows do compete, after all.
Just throwing that out there.
