No, very few games you can learn everything about it from actually in the game. There are some, but most mmorpg's have a forum or a form of wiki for players to reference to.
Try playing any multiplayer sandbox - Wurm Online, Terraria, Mine craft (not vanilla), Eve Online, without looking at the guides or a wiki and it's extremely difficult to get anywhere quickly. The same as is it in haven - not impossible, but difficult.
That said, some custom clients do have an ingame wiki.
There are a few games (eg Runescape) where you don't need a wiki to play, but I have found those games to be pretty shitty and lacking in deeper content. I also prefer having the butloads of text required to explain things out of the game and in a browser.
So no, it is not my personal opinion that a good game (of this type) must need no documentation to play efficiently.
