The Path of Exile wiki moved off fandom to https://www.poewiki.net and has been very successful. If I google "path of exile wiki" it's the top result for me (in an anonymous window). The creators of PoE even agreed to host the new wiki. The move to the new wiki was heavily supported by the subreddit for PoE, often pointing people that posted links to the fandom version to the new version. I remember there being guides to on how to block fandom with ublock, how to add the new wiki as a search provider in Firefox, etc.

Yugioh wiki also moved to Yugipedia a long time ago. It was a contentious decision at the time but absolutely the right one in hindsight. The obnoxious autoplay videos ads, horrible mobile layout, forced adoption of styles and features all contributed to the decision.
