Reminds me of the person who had a 60+ page google doc for lore on an RP. Also remember everyone calling it a "nice story" since it looked like there would be a hell of a lot of limitations and stuff that could happen within said 60 pages of lore.

In my opinion, RP lores should be simple if their original. Give people outlines and maybe a few examples like:
[quote]In this RP, tech will be around the mideveal era although there will be various elements of magitech although said magitech is more uncommon understandably. Examples:

- Enchanted plate armor
- Magic-powered Golem
- Special lenses that focus the sun's beam into a weapon
- etc etc etc[/quote]
(Personally I find it rather annoying when an RP says "we have tech at level X but with a twist!" and doesn't go into any detail leaving everyone wondering what the actual tech level and limitations are/)

In another sense, it could just be that RPs aren't the best way to introduce copious amounts of lore, at least not at once. Lets take Harry Potter and Warhammer 40k for some examples. HP has a lot of lore and world building in it, but its split across seven books and never just thrown out at you. 40k has an even larger lore and reading the wiki would be a pain in the ass, but I mostly learned mine through youtube lore videos which broke it up into easy to understand chunks.

tl;dr - Make a solid but simple lore base in your IC/OOC then build on it as the RP grows.
