A useful race and culture is started with this entry. More detail would have been useful as well as links to the 'cousin races'. I've had trouble believing a race that abbreviates everything would make good ambassadors as the devil is often in the detail, admittedly most solutions are pretty simple. It sounds to me like they would have to have an impeccable moral compass if they were to make good diplomats as well. I enjoyed the start but feel with a little more effort they could have been fleshed out better.
I really like this idea. As was mentioned, I think it brings reason to the chaos. It answers the question about why a monster would sit in a room miles underground waiting hours, days, weeks, months, or years for the PCs to come along. If I were to use this (which I probably will, just not in the foreseeable future) , I would probably go with the reality 'tv' option. I would create a list of all things entertaining about a reality tv show and grade the PCs' popularity by it. Such as inter-party conflict, romantic tension, moral dilemmas, eating something disgusting, flashy moves, battle cries, coolness, etc. Then a PC with a high popularity rating would be more likely spared from death, given the coolest treasure, or placed in the most awkward situations for the benefit of the viewing public.
Nice... sick in many ways but usable. I wonder how much the PCs will groan when they find out.
