@Sunny I feel you on this. I love -- love love love -- some world-building, but the amount of info needed is not easy for something that doesn't have an RPG book handy that people can get and read through.
That said, most games involve at least one RPG book that someone has to get and read through. (Or a television series to watch, or a series of novels, etc.)
It is unlikely that even if you put down a lot of details and information on a wiki and MUX, it still isn't going to be as much as you'd find in your average RPG corebook. Even if most people skim and flip around, they usually end up reading about a third of it, and many read the whole thing. Others read multiple books.
If people can read for WoD or any other game system or setting, they can read for yours. The collective freakout over being asked to read detailed setting and game system information on a wiki -- especially if there is no corresponding media to watch or read necessary -- is just a little silly. (By which I mean it's a lot silly.)
Have summaries, with further detail people can delve into if they're interested and/or want or need more depth for their character (or for other characters they're interacting with when and if it becomes relevant), but the people who claim to be overwhelmed by unnecessary details are often enough the same people who have read -- at the very least -- the core WoD sourcebook from cover to cover before they play somewhere, and there's some bullshit to be called on that particular complaint for hypocrisy.
If somebody can read a corebook for an RPG, which most folks do, they can read a game wiki.
tl;dr: organize the info well, and anybody who complains there's too much information who has ever made a character on TR or FC with a zillion splatbooks required for reference gets an anime-style mallet to the skull, which will conveniently appear out of nowhere for this exact purpose.
