I still think that the premise of Kidnapped! could make for a good LARP, but I clearly need to write character sheets. I don't have time now, but that may be a summer project. If anyone is interested in working with me on that, please let me know; I'd love to have a co-writer or two!
Other games I'm thinking of playing are as follows, though I probably will have to leave some time free for work during the weekend.
Friday night: Timelines, since I love time travel stories
Saturday afternoon: Concordance Station.
Saturday night: Resonance. I had a similar idea for a LARP once, and so I'm really interested in seeing how this plays out. Also, I've enjoyed other games by the authors.
Sunday afternoon: Costumed Henchmen. People at SLAW seemed to enjoy this.
