One-Shot Adventures For GURPS
It's 1shotadventures.com, and I'm impressed.
This is an amazing, well-organized site with dozens of original, illustrated one-shot adventures for GURPS and other RPGs. By my count, there are 44, all with GURPS stats but many statted for other games as well, mostly Call of Cthulhu and OSR/D&D. This treasure trove was created by JC Connors, who has been with GURPS since the beginning and is still keeping up (one of the latest features on the site is a review of Fourth Edition Revised).
And everything is free.
Oh, you want the URL already? You're not even going to read the rest of this posting? Very well, here it is. You are actually not making a bad decision . . . but I'm going to keep typing. Because I like what I see here!
There are VTT tokens for several adventures; links to a number of well-crafted YouTube reviews; some specialized character sheets; even indexes by both system and genre! There's also a FAQ explaining the purpose of the site. (tl;dr - "You should play games. Here are some. Tell me what you think.")
If you play any of those systems, you should definitely visit the site. And seriously – leave some feedback for JC. That's the only payback he gets for this generous donation to the gaming world, and I hope he continues to get plenty of it.
