I just re-read the OP and realize the last criteria is that botting be allowed so he can read a book while his character mines.

That, combined with the "no permadeath" issue, eliminates RPIs entirely. Botting isn't allowed, and in many cases, can result in your character dying since you're not paying attention to the scrab in the next room looking for its next meal. In an RPI, it's expected that when you're logged in, you're paying attention to the screen, and if you want to read a book, you log off and read the book. On the other hand - skill-grinding isn't efficient, and farming for loot has its limits (the shopkeepers will only buy a certain amount of stuff in any given period of time and your character can only carry so much excess before he can't move even 1 room away).
