So I'm thinking about trying something I wanted to do a couple years ago but didn't have a good system or structure for, but think I do now.
A series of short-term, limited-run survival horror stories where there's a set beginning and end. A mistake I made the last time I tried this was having everyone make whatever they wanted, which is fine on a long-term, ongoing game but hard to pull off on a short, focused story. This time I'd be treating it like a LARP at a convention, where everyone picks or gets handed a pre-made character to play for the weekend. I would go roster-based, so characters are pre-gens - they'd all have roles in the plot, ties to other characters (good and bad), and come with goals to accomplish. Stories would be anywhere from a few weeks to a couple months, depending on need.
No, it wouldn't be for everyone. People looking for long-term character development, growth and XP building would hate it, I imagine. But it would be a game where you could do minimal reading, pick a character, and get guaranteed plot X many times a week. The finite nature of things means there would be real consequences and risk, anyone could die at any time, and anything could happen. I liken it to the difference between The Walking Dead and Breaking Bad. Regular MU*s are like the former - ongoing, most key characters are safe, the threat and danger feels artificial. This would be like the latter, where no one is safe, there's an end game planned, and how you get there is the thrill of it.
I'd use the modified version of Slasher Flick I'm running now on Welcome to Lovecraft with a few last tweaks. It's great for a game where fighting the evil is a deathwish and surviving is what matters.
Would there be interest? I wouldn't want to make a bunch of characters and story if no one really wants it.
