I’m not sure that it’s anything close to an OSR game in terms of mechanics, but for some reason F. Douglas Wall’s new Adventures in Oz RPG just caught my imagination. Perhaps it’s because I’m developing quite a collection of kids-oriented RPGs (this one is said to be suitable for gamers of all ages), but I’m very much looking forward to reading this new release. I’ve read through his blog posts on the design process and it seems like he’s combined a lot of thoughtful design with an obvious love (perhaps “obsession” is the correct word) with the original source material.
His blog is now linked over to the left, and there’s a lot of neat stuff in there, not just RPG, but related to the original Oz books (which, a quick flip of the DMG reveals, were not in Appendix N as I had originally thought) and a lot of other related topics. I think it’s worth a look.
