Seen on DriveThruRPG: One Starry Night, an adventure for Cthulhu Live:
Unlike previous Cthulhu Live scenarios, which have tried to do a theatre-style larp using an adventure larp system, this one is actually an adventure larp where the players bring their own characters. It needs 5 different locations (though most are single rooms), and a handful of crew (3 minimum, but the need to prepare multiple locations means you probably need an extra couple of people to be safe). The plot is a simple tunnel of fun, starting with an academic with a break-in. While it is pitched as being a modern scenario, there’s no computers or even any thought of them (one early clue is the sort of thing where computers plus internet means you go straight to the required information. Not that it especially matters). It may therefore work better as a 1920’s scenario, and this option is suggested. It would at least save the GM from having to create fake social media accounts for some of the NPCs. Looking at the outline, it looks like it would run OK and deliver an evening of fun, and at $2, its worth buying just for an example of how to put such a larp together.
