I just want to point out that wiki is maintained by the fans, not Selebus. Sel just endorses it and linked it in the game so people don't need to look into other pages (often full of ads etc), though he still thinks game should be played without a guide.The wiki, however, needs to be updated since it is the official source for the guide button in game.
Saying all that, I'd like to encourage everyone to update the wiki if they see some information is missing, or if they decide a page requires more info/synopsis etc. You can't expect that one or two people can keep it updated with all the changes every update.
