So it would be about some people waking up somewhere, they don't recall what happened. The place looks like where they came from, but in some kind of more sinister way, with some things being unusually different. (Like the town would look old, empty, devoid of life, but yet look similar in some way, if that makes sense) They would eventually find clues about what happened, why they are there, and that they are helplessly loss in another universe, and I'm also thinking about having one of the character (you don't know who) slowly losing his mind, and feeling like he has to kill the other, and then it could be about getting out of that universe (while gathering clues on how to do that) and or finding who it is (or maybe it's not someone but some things pretending to be a human (not an actual player) and trying to mess with them, putting them against each other.) It would be in the modern time. So yea, any ideas?

Interested :)

Sounds pretty interesting.

Would the people living in that city still be there? And if so, would they be normal people, not knowing what is going on? Or would they be part of the whole wrongness?

This is highly appealing.
