Congrats on getting something done in 48! I had a few thoughts while reading:
- Interesting cover... not quite sure what is happening though. But it drew me in.
- In the welcome to section... Tell me what I'm should be doing rather than what I shouldn't be doing.
- Wow... you have a lot of setting in there. As someone new who does know the world, maybe bullet points to begin. Keep what you have but maybe move it a bit further into the document.
- Character creation is interesting. I like that players can build their character how they would like. I wish there were drawbacks to building... purposeful negatives.
- I like the concept of the d20 rule... but I think you should encourage players to use different dice. In the example you give us, it would make more since to use a d6 or d12.
- Nice descriptive rules for determining actions.
- REALLY LIKE YOUR WORLD MAP GENERATOR! That is super great!
Nice job overall! I would say on the next pass, focus on layout to onboard players easier.
