Open questions to discuss:

Spoilers: How to handle setting spoilers, reveals, and wiki updates?

Especially since I want to make it possible and easy for players to propose their own feats, spells, classes, and magic items! And this might require some setting spoilers to understand why the GM says no, and how to adjust the proposal to match the setting.

Character Advancement: How fast do we want characters to advance?

We have roughly three tracks of advancement: leveling up in the traditional way through gaining class levels, improving your gear and equipment, and (eventually) mythic path progression. We can stagger these different tracks---for example, improving gear and equipment can be done out of sync with leveling up, and mythic path progression can also be done in a level-independent manner.

Do we want to care about experience? Given the crack-smoking-monkeys table, this might not really help is in a significant manner (except allowing players that miss out on a few sessions to catch up eventually)

Based on the answers here, the GM will need to update some tables (currently 'starting at level 5 and every 2 thereafter', might need to become starting at 'level 3 and every 2 thereafter' if we go for slow advancement, just to make sure that we get to 'the full thing')
