I know the current policy is that the only citation links allowed are from the game and Solmare's official pages. However, with the recent discovery of the Korean version of WH, I think we need to make an exception for information regarding the Korean version specifically.
Because the Korean app has been defunct for several years and all official pages have been deleted, the only evidence we have are blogs and various non-official sites. My concern is that if we stick to only official sources, we will not be able to properly cite information regarding the Korean version, which violates the citations needed rules and will become a huge mess.
There's so little information on the Korean version as it is that I think it's fair to say that it should be given special treatment in regards to citing rules because it's very much lost media and what still exists needs to be archived immediately before any more information is lost. Not to mention we need to be able to track down information about the Korean version, and if we aren't allowed to cite non-official sources, we may lose or forget the sources that DO exist.
The sources I've found have corroborated each other and things like summary text was very, very likely taken from the official sources when they were still up since other pages on these sites match up to what we have currently on official WH sites (ie the page for the English app has the same summary as the App store page for the English WH)
So I ask that we make an exception of the official sources only rule for the Korean version only. The Korean version is almost completely lost to time and we need to document it as soon as possible, but we need to include the sources where we've found what little information still exists.
