I’m not so sure how else to do the whole “traditional career mode” while also integrating post-launch content like new cars/tracks. So I think GT7 does this pretty well, between adding new rounds of pre-existing events, adding new events such as via Bonus Menus, at least one new mission set, the Master licenses, and so on.
I’d go as far to say that there’s not much I want that can’t be added in something like a new Bonus Menu or mission set. I do feel like we’re definitely due for the latter, even if we don’t count the 24h races that they mentioned early-on.
