Hmm...I went with other. I like the idea of it depending on difficulty level.
Easy - Weeflerunner - you die, you respawn at the hospital and carry on, less a few euro.
Normal - Corporate Wage Slave - you die, better hope your TT account is paid up, else you risk waking up on a ripperdoc's slab, about to be harvested for organs and cyber. Or perhaps getting repaired, but with a few...surprises built in. Maybe even waking up to find that you have been "generously" repaired by someone lik Arasaka or Militech and all they ask in return is that you do them a favor or two...and don't worry about the discomfort at the back of your neck...
Hard - Hardened Veteran - You better have that TT paid up or you can expect to be harvested on the spot, in other words...reload previous save game.
Iron Man - Cyberpsycho Maximus - you're going out in a pink and chrome mist, because if you are tough enough to play here, your enemies are coming with the BFG's. Get ready to start a new character.
I would also go so far as to suggest that even if you do have TT paid in full for a platinum account, the harder difficulty levels make it less likely that they can get to you in time. Assuming you do get your TT card snapped in time, on harder difficulty levels, you could expect things like your foes putting that final bullet through your skull or the scavengers moving in more quickly after the firefight.
Something to think about, anyway...
