I think this came up as a question earlier...
Here are some things I have in the hopper. I may get ambitious and try to run them at a local con, as well as with my guinea pig players. I'll probably end up posting pleas for help and reports on the various lists.
- HQ rewrite of my "Masks of Fu Manchu" adventure serial game, set in the 1900's (sort of).
- HQ version of a Boarding School (Billy Bunter style) or P.G. Wodehouse (Wooster & Jeeves) game - some pals ran a very fun LARP based on Wooster & Jeeves.
- HQ version of a Silver Age supervillain game, set with off beat characters from Canada: LuLeClerc (a Lex Luthor type), Mighty Mounty, Wonder Canuck (and sidekick Wonder Beaver), Le Ours Blanc, etc. The original was a fun LARP.
- HQ version of a Jack and the Bean Stalk as a HeroQuest. No real setting,
Probably some more - I play a lot of one-shot table top games and LARPs.
