Someone said that “if you can run Keep on the Borderlands with it, it’s OSR”.
I’m pretty sure that’s not true. I of course immediately tried to think of the most story game way to run B2. M...
@nprofile1q... you can adapt B2 to basically everything because it's such a classic setup. An adventure base/human power centre and another collection of humanoid tribes/alternative power center. Assorted stuff in the wider world. IMHO it's not even needed to make the caves the bad guy area, as it's more of a collective of tribes (with a funky church). One could e.g. easily do it the other way around: Caves as the good side, keep as the bad guys.
