Moving my discussion from the NintendoWiki thread and Wars members responses. There is a point in the life of a wiki and it's series that is is covering, where you simply can't improve. This mostly applies to the game series that end or haven't seen a new game in a long time. (Such as Wars Wiki, and Wikibound, and Golden Sun Universe really) It's unfortunate, but the truth. Whenever that point is reached,which hasn't happened to any of these wikis yet though GSU is getting close, the only thing left for these wikis are maintenance. We will need to keep this in mind.
When a series dies off, the fan base will be lacking greatly. This is the problem with Wikibound and Wars Wiki. They don't have enough of a fan base to craft a fully developed wiki. So, I'm not sure that as NIWA, we can really help them very much.
