You may not know this but there is a forza motorsport wiki on wikia. If you don’t know what wikia is, it’s a website like wikipedia but you can create mini wikipedias on certain topics (i.e. video game series, tv, food, real world stuff, movies, etc) without having to have maybe one wikipedia page barely outlining it. The forza wiki has all the cars, tracks and dlcs for each game. There is achievements and stuff. I’m posting this as there isn’t much appearing on the wiki activity that isn’t me. There is 641 pages and several active members and admins. Link: Forza Wiki | Fandom
