I've heard of this alliance of wikis called NIWA (Nintendo Independent Wiki Alliance). Three wikis , Mariowiki.com, the Pokemon wiki, and Legend of Zelda.org have come together and form a union of Nintendo based wikis. They state they are against corporazation. They have convinced several Wikia based wikis to join them and move from Wikia and form their wiki similar in style of Wikipedia. I have seen this happen to four wikis. Recently starfox.wikia.com recently moved off Wikia to do this, because they dont want to messed around by the heads of Wikia.
