My ideal RPG: an 8-12 page booklet with a moderm infographic-style design that explains all the rules. All the reference stuff (monsters, magic, feats, classes, playbooks, you name it) as cards, bigger or smaller, depending on the need.

The goal would be to make it as accessible as possible, ideally to be picked up and learned in 15-30 minutes. Just like board games. Some publishers did try that in the late 80s, but it went nowhere.

If I get angry enough, I'll do it. 😀​

@tomo there's been some activity in RPGs oriented toward no-prep, pick up and learn style play in small form factors in the "indie" RPG world. Consider _Lady Blackbird_ which provides a ready to go system and adventure in about the page count you reference: http://www.onesevendesign.com/ladyblackbird/

Yeah, I know Lady Blackbird and it's hacks. It's one of my inspirations.
