Chaosium (publishers of Call of Cthulu, RuneQuest, 7th Sea etc) are having a warehouse clearance sale, with items being 15% to 66% off.
Here’s a list of stuff I personally recommend.
Alone Against the Flames, A solo Call of Cthulhu adventure. Learn how to play CoC 7th edition for the price of a coffee. SOLD!
HP Lovecraft’s Dunwich A Call of Cthulhu Sandbox, with a couple of supporting adventures. I had this in the 90s and foolishly let it go, but by gum, its mine again at a bargain price
RuneQuest Classic. A cleaned-up version of RuneQuest 2, without losing the original’s essential charm, with about 22 extra pages from magazines from the period, in a robust hardback. This is my Whitebox.
Borderlands and Beyond. Want a starting campaign for RQ? This is it. This is a collected edition, Borderlands + 2 other supplements integrated with new art from fan favourites. I had the pleasure of buying from Rick Meints, the publisher, at a convention in the 2000s.
13th Age Glorantha. Want to get into Glorantha, but overwhelmed by RQ and have a group that is more into D&D? This is your way of getting your Glorantha fix. Also worth getting if you are an old hand since it positively purrs in play 🙂
Khan of Khans. The easy to play card game intro to Glorantha. I played this with our H when he was around eight, he came away wanting to know more about Glorantha. Result!
