I am not a BRP fan (at least for fantasy, it's okay for CoC), but there is an interesting product, Ki Khanga, a Sword & Soul based game like Spears of the Dawn. To me the best way to promote diversity in the hobby is to quit talking about it and put out diverse products, in this case, a fantasy Africa game.
OfficialA Light in the Belfry - Apparently one of the 2e era audio adventures, this time for Ravenloft. No audio though. 32 pages, $4.99
AC3 The Kidnapping of Princess Arelina - TSR really had a thing for paper miniatures for some reason (also in their Indiana Jones game) and this was an attempt to add them to B/X. $4.99
AC8 The Revenge of Rusak - See above. And Rusak's Revenge is much catchier. $4.99 and 16 pages.
Savage Baronies - Another audio cd enhanced product, again sans the audio. This time it was an expansion for the Savage Coast, which was sort of a mini-setting of Mystara in the 2e era. $4.99 and 96 pages.
RulesMicrolite74 3d6 Edition - 68 pages, Another variation of the Microlite rules. PWYW 68 pages.
A Field Guide to Hot Springs Island - I have no idea what this is exactly. An adventure? A location sourcebook? Fiction? Seems like it's all of them. No idea what rules it uses but it says "OSR" in the category, so who knows. And at $19.99, I won't be finding out. It's 240 pages, though.
Friday Freebie Enhanced 6-30-17 - Smallish underground temple, looks like. $1 for enhanced version.
