so let's say this: When you die, and you stay dead for 1 minute straight, you are forced out of the game and you get a screen saying: you cannot be resurrected no longer.

heh, I know this is a long shot, but it would seem more realistic towards the fact that you actually collapse on the floor with injuries .

And as for resurrection, it should have some percent chance of working and not working. I'm not sure about this one, shall we discuss?
