That there's several different groups all working towards their own goals within the game. Each group has their own very valid reasons for wanting to win by their own conditions, but the best possible outcome is likely one of compromise. And sacrifice, too, since there's no guarantee that the Players will be brought back at the end. And even if they are brought back the Reapers will not get that same consideration.

And...it's hard to go along with that. To accept that I might be gone forever for the sake of a couple-dozen people I barely know. Especially when more than a few of that number would not spare a second thought to my life if they knew my role in the game. It's hard to be willing to give up so much for people who, albeit incidentally, would not be sad to see you gone.
