Good small systems


Hi all,

I'm working with a prison book project, where we mail books to prisoners who request them. We get a lot of requests for RPG books (especially system rules). I know most of them are probably asking for The Players Handbook for 5e or something, but I want to find something like Knave we can print out for prisoners for very cheap.

Are there any other smaller light weight systems youd recommend (under 10 pages)?
