Does this mean self-hosting the wiki?
Because that increase the barrier of entry by tenfold as a lot of publishers/game studios do not host their own wikis.
Fandom hosts a lot of wikis for long forgotten nich’e games and with these games there usually isn’t enough interest to move to another wiki. When it comes to these wikis theres rarely if ever a team behind updating the wiki and more often than not the content is just being updated and maintained by random invidividuals who just happen to be engaging with the content at given time. The very low barrier of entry makes this possible as you don’t really need to join a team to edit pages or even coordinate with other people.
When playing one of these games I like to record and share some my observations and findings about games mechanics etc but more often than not the only wiki I can find is fandom wiki that is either incomplete and possibly even abandoned. I cant be bothered to create my own Wiki for these games so I’ll just start editing that one instead because it’s easy, the foundation is usually already there and I don’t need to bother taking any sort of responsibility/mantle of maintainer or admin.
While Fandom may not be the most optimal choice and there may be better ways to host wiki out there its still better than some obnoxious google document or poorly formatted steam guide that no one else can edit.
If the story or it’s presentation is lacking then it’s something a lot of players may want to know before buying the game.
Now how much it should affect the actual score depends on the reviewer.
When it comes to Armored Core 8/10 is actually 1-2 points higher than the series usually gets.
The game is no Dark souls or Elder ring but not bad for previously rather niche franchaise.
