I *love* when games don't explain themselves.
I've seen a lot of game design discourse saying games ought to be self-contained. If you have to google it, the game isn't providing you the information you need!
e.g. Minecraft without the wiki and armies of video guides would be nearly unplayable. Similarly, the Dark Soulses are exceedingly cryptic and generally demand research in order to play effectively.
That this is a flaw seems to be taken as self-evident. But I don't think it is.
