Another set of “murder mystery” scenarios that are actually larps, much like Freeform Games. These are called the Confetti Cases:

Some of these look to be quite suitable for a larp convention like Chimera or Hydra, or for a one-off larp like the Friday Night Larps in Auckland. I haven’t read any of them so can’t comment on the style of game though.
There are some curious gender mixes in there, and not just the game for 20 women but also a number that are quite heavily weighted male or female. The scenario called Nightmares of Napoleon looks like it may be quite appealing as a convention game, it has 15 male and 20 female characters.
Some of the small games might be good for parties or to run in areas where larp is still getting started, as their genres are accessible and costume requirements low. Like Violence in the Vineyard, which has 4 male and 4 female characters, Atlantis Found, or Time Travel Tales.
