Well, I may not have all the fancy stuffs like some have to try to get you hooked into playing, mostly because this is just an idea. So bear with me on this.

Okay.

So if any of you have seen the 1982 horror movie "The Thing", I wondered how cool of an RP the concept would make if done correctly. For those who haven't seen it, the idea goes: A group of scientists stuck at an Antarctic research outpost are slaughtered one-by-one by an alien creature 'the thing'. But this isn't any ordinary or conventional alien from your typical sci-if horror flick. This monster has no form. It's a pile of flesh and bone that digests you alive and then uses your DNA to replicate your form and behavior, masking its identity for its next unsuspecting victim. Now, as you can imagine, the paranoia in this movie is off the charts. Nobody knows who's real and who's a thing. Not even the viewer. I thought, with some sort of mechanic, this could make for a really cool RP that invokes the same paranoia into each one of you players.

So I decided, after a long time of inactivity on this site, to peruse to see if anyone has done such a thing but to no avail really. I still don't have a clue if someone has done this concept, but if they have, well, here's a new one. Possibly. So maybe with some support, this RP can become a thing for us to enjoy. Lemme know if you're interested. Any ideas are strongly welcomed as well.

It would ruin the rp if everyone knew who it was even though our characters don't. In the movie it showed us which person got attacked so the viewer new but presumably the characters in the movie didn't. Find a way to this...

ah, don't worry. This is the main selling point I'm after. You're right, it wouldn't be any fun if everyone knew who the thing was. This is why I'm considering it a (lite) tabletop game. Not complicated, but some behind-the-scenes stuff is going on. I'm checking out a fan card game that's based on the movie that uses a mechanic like that, and I think I'm going to try to interpret those rules somehow as a base.

I'm gonna lay a delicious bump for this thread. Buuuump.

I would definitely be interested in this, it could be great if it was done properly. However, I've never played a tabletop RP or anything of the like so that might be a problem. I'd be willing to learn, but you might not want a beginner along!
Also, this should have 10x the interest it has at the moment...

@NowIGiveUp Don't worry, it's not going to be a full blown tabletop. Nothing is going to be complicated. For what I have been thinking so far is all the players have to do is rp normally. I however, decide who the thing will be and pm that person. A series of my public dice rolls (though nobody will know what for unless I pm) will determine the outcome of things where I will act as a narrator explaining the events that have taken place. Oh. And of course, the thing will spread unbeknownst to everyone who is not one. Spooky.

I absolutely agree, if I do say so myself. It's the perfect scenario for a good horror game

I would be very interested in this, also have you ever read "The Things" by peter watts, its basically the movie from the perspective of "The Thing" its very interesting.
