It's interesting to think you're averse to the 'uncomfortable' interactions between a stalker/murderer in one respect, but not another. Any tot, cling, or vamp may get an assassinate target and choose to stalk/murder their prey. I know it's happened to me plenty of times, a tot has followed me around, someone I don't even know... trying to talk to me and be 'friends' only to gun me down later.
Positives of the obsessed antagonist as I proposed (mid round auto-tot style roll that affects a living character)
Provides some excitement for the round to living players
One person is now obsessed, has to break away from their normal work to spend time with someone else. Hard to hide/justify this at times.
The victim may start to notice the stalking and attempt to hide/escape/inform security
one more thing for sec to deal with
Adds some role-play value between players
Assailant/victim - Talking to each other as the assailant spends time with the victim to satisfy the goal
assailant/psych - Talking to a psych as a security-mandated cure for those who are caught (it would be nice to actually make psych useful for once)
assailant/sec - interacting with sec as part of the arrest or investigation
victim/sec - same as above
sec/sec - Discussing with each other about the security process
Having a single victim is not a huge stress to the station, it would be hard for this antag to get out of hand unless someone went to far such as max-cap or bombing, but that's against the rules anyways.
Negatives:
Some people may be uncomfortable with being stalked or stalking
If playing a stalker makes you uncomfortable, don't play it.
If you are uncomfortable with being stalked, log out of the game. Our current antags stalk and murder on a daily basis.
This seems similar to a tot role
In a sense, yes, it's just an assassin role with amusing goals.
I propose they get no TC
I propose we make it hard, not a 5 minute spent together goal, but 10 to 15 minimum time. Multiple pictures, together and alone, Messages via PDA, a piece of clothing? Make it noticeable so that when you are caught with a photo album that always contains one person in particular, it's undeniable.
I don't propose a carbon copy of their game mode. I would like to see it executed as an improvement of it, something that adds a bit of spice to a round. Let it roll at 30 minutes in to see if we even get one or two obsessed people, then roll who gets it. Doesn't always have to happen, maybe 10 or 15% chance that the round even gets an obsessed. I think it's a fun idea that might add a bit of extra richness to the game.
