Regarding the idea, to be honest, it's a bit boring. Sure, serial killer, but we are talking about roguelike here. How deep will your simulation go? Will each character have sets of AI to govern their daily behavior? If yes, how much combination? How will police investigation simulation works? Unless you are shooting for the star with a ridiculous simulation the game would get boring pretty fast. Personally, if I want to play a game of serial killer I would want to be able to observe my victims, learning their habit, etc2. Lazy or randomized behavior would kill the game.
Thanks for your opinions!
Right now I am more thinking about making "Fallout Roguelike" something that would be blend of Fallout 1+2, Wasteland, Stalker and The Road.
Huge procedurally generated world, with traveling just as in Fallout 1&2 - big map divided in locations. That would be mostly scavenging and surviving sandbox game, different every time you play it.
Based on this, basically the map would work like
Cataclysm DDA? But instead of zombie, normal people? I say the scope is too big. If you are aiming for complex simulation as I mentioned, this kind size will kill the game(literally, as in crash to desktop) because the game need to emulate all movement independence of player action.
Cataclysm DDA has some sort of reality bubble in which only in it will the game simulate behavior. It's fine there because, hey zombies, without living things they most likely will just drool and sit. But people? If my target is working in Burger King thousand of tiles away, the game need to simulate "him" so that he will come back home at four, using certain routes etc2. And that's just one person. Try doing it for the whole city and bam, CTD.
And based on the poll, you are going to sell it yes? Commercially? Do yourself a favor, tone down the sadism and senseless murder and this game might go to Steam. My suggestion? Do it like Dexter or Hitman. Make it so that the target of killing is not random and instead based on some criteria. Modern assassin game would work much better and give some sort of goal instead of random murder. Maybe news about corrupt people for Dexter route or contract for Hitman route, or both.
