Just -once-, as a GM, I'd like to see a player make a mentally unstable character who isn't some kind of extreme monster who brutally murders everything, especially for no reason. Just an individual with some pretty serious flaws would be nice.
I'm never going to get this, mind you, but a ferret man can dream, can't he?
Not related to mental illness or anything, but this reminds me of a character I made I was rather fond of I didn't get a chance to really play much before the RP died where it was a fantasy setting where the rare individual has magic (or as it's called in the game, a Talent) that has a tangible opposite and equal reaction to using or some other kind of drawback. My character was a teenage girl whose entire life was basically under the watch of the church who had a talent of altering people's memories (such as adding memories that didn't exist, removing memories someone had, changing their perception of ones they had, and so on. An example used in game was convincing a man who could help her and another girl escape from a life under the church's watch that they were siblings and he came to the city to help rescue them), but the effect it had on her was that every time she used her Talent, something would change in
her memory and she would be none the wiser, which led her to start writing down things she remembered just in case there was an important detail that might have been erased or changed. Sometimes something would be fairly benign that changed like honestly believing the King was a literal sheep, or that the sky was purple, but other times it would have a lot more dire and tragic consequences like forgetting that her parents existed, believing that one of her classmates had tried to kill someone, and so on. The reason she wanted her freedom from the church is because she was being pressured to practice her Talent a lot over her life and it was becoming a Ship of Theseus scenario where if all of her important memories were changed from before her Talent manifested, would she still be the same person? She wanted to live a life where she didn't have to live in fear of her own Talent (or have people live in fear of her; in the church, she had virtually no friends because people were terrified she'd change their memories), but to get there, she'd have to use it a few more times. I was going to have this be randomized as the game went by by writing down a list of possibilities and rolling a dice 3 times and using what item it landed on for the effect that would happen to her over the game. It would have been really interesting to see if she would have been the same person as when the game started, and that was really exciting.
Ah well, maybe if the game gets rebooted.
Also, as for what I want to see in a game, it's more a series I want to see adapted to a roleplay, creepy paranormal shit and anomalies and all that. If somebody made a Metro 2033 themed game, I'd love them for eternity.
