This topic has been touched on in the main forums. I'd like to address it here with a game management approach, not what we want to read when joining another site. Just our opinions as the creators of worlds.
How much lore is too much for a site?
Is it site dependent? In other words, does the amount of lore relate to how intuitive or user-friendly a world or realm is?
Should we expect new members (and old, in some cases) actually read everything? Put in the work to learn the world and build a great character?
Relates to #3: Are those of us with lore-heavy sites expecting too much of new members by having a lore-heavy site?
