Which video game has the best player-edited Wiki?

I'd have to say Minecraft. People who edit it's wiki put Really lots of effort into it, making it detailed, broad but concise and easy to read. Most other games though have half-assed wikis that are no good.

Minecraft is quite possibly the most extensive and maintained.

RuneScape has an extremely detailed and well maintained wiki as well.

There are also other fan sites about it.
