Yes, it's a bit of a misleading title because plots are already part of the game in a MUSH environment, but it gets across what I'm trying to say.
The project I'm working on emulates TV urban fantasy as a genre and one of the conventions of that genre is the Scooby gang, (or the pack or family or whatever). Few protagonists truly go it alone in the TV version of UF. Which is a great thing for a MU, because group play is play that tends to heighten player engagement for several people at once and often spills out to other groups.
To encourage that kind of play while avoiding punishing those who do wish to be lone avengers of the night, we are likely going to be giving out plot tokens on a monthly basis. Accumulate enough tokens and you can turn them in to get a staff-run plot, personalized to your player or group. We are tentatively looking at one or two tokens a month per character and a base cost of ten tokens per personalized plot.
For the purposes of our game, each of these staff-run plots would be the equivalent of an episode or two of a TV show in which the season story arc is furthered, rather than just a 'monster of the week' episode with minor story elements. (Though we do have some awesome plans for monster of the week plots that won't even require staff involvement except for loading up a plot dispenser object with NPC+Location+Situation Madlibs blocks and then reviewing the logs for future plot hooks.)
Players can pool their tokens within a particular group as long as they are flagged as belonging to 'X pack' or 'Y family' or 'Z coven'. So while a hardcore solo player can reasonably expect a personalized plot every five or six months of play, a group of three to five players can expect one every month, storyteller time permitting.
My personal thought as the game Producer/HeadWiz is that we want to encourage folks to buy into the genre conventions and game events, rather than freezing out those who don't. And the plot tokens can be a useful meta-currency for rewarding behavior we want to see or for taking up roles we want to see filled.
Have any of you tried something like this before? Or played on a game that did? Did it work? Would you, as a player, appreciate such a system?
