The location, modes, and featured cars are continually changing in Forza. I’m lagging on the titles and will probably skip Forza Horizon 5, but FH6 has great reviews on launch. While I can guess you aren’t into cars/racing like that, I guess I can’t really differentiate it from human sports games as much as I thought I could. A new football game has the same field shape, the same rules, and mostly the same teams, but just updates the roster and maybe background appearance? I don’t get it. But I can see the correlation to racing games if driving is a chore (not me) and if you aren’t up to date on the latest trends in cars (me). I guess both really come down to whether or not you can empathetically experience the game as something you actually want to do.
