Not sure about the whole addiction angle, but that's just me. I would find it more terrifying that the reasons that they were selected to be more arbitrary; bad things are happening to them not because they deserve it or have a problem or require any sort of correction, but because they were simply "convenient." ("Why am I doing this to you? Because you are here. Now, this next procedure is rather painful to endure, I'm told, so please try not to thrash about too much? It's distracting when you do, and I can only tighten the restraints so much. Think of the things we will learn from this, how humanity will benefit! Well, not so much you personally, of course...")<br/><br/>Before getting too far into the world-building, might I suggest deciding who is playing what first? At least generally. That way, a player doesn't have their character forced into a role or a situation they'd rather not play out. That way, you have a better idea of how far the researchers are willing to go in their pursuits and how much of any given test the subjects are able to endure. Given some of the material proposed in the earlier PMs, I would suggest having the actual story in Extreme. One you start talking non-con body part replacement with the potential for visceral gore, that goes beyond a bit of bondage.<br/><br/>Another thing to focus on is the end-game. Sandbox is good. Sandbox is fun! But having some sort of goal for the story in mind sometimes helps people focus on moving forward instead of just being bogged down in scenes. Any good story needs a beginning and an end.<br/><br/>All that being said, I would not be able to join in on the fun at this time. I do want to thank you folks for including me in the PMs! Right now, though? Sorry, too many brands in the fire with a couple of others set aside waiting for me to get to them, and as much as I really, really want to play out this sort of story, it's just not fair to my extant partners. I would have to drop at least two (preferably four) of my active solo RPs in order to dedicate the time needed for a group RP, and that's just not happening. If things open up in the future and this is still going, I can take a measure of things then, perhaps? Or do an occasional cameo scene later down the line: The Director paying a visit to see how progress is coming along, a subject suffering a gruesome death in front of the others, the poor bastard of a janitor who has to clean up everyone's messes... But even that would be in the future, not anytime soon.<br/><br/>Have fun!
