A Battle Pass system.

well they generally use such system on fps games , imo it wouldn't fit to nfssa

I understand why you think that, since most games that use this system are based on shooting gameplay, like pubg,fortnite or world of tanks. But something like magic the gathering arena uses this as well, on a name of mastery pass, so i don't think it's exclusive to a certain game type. Also nfs sa has some features already which isn't fit the nfs theme (e.g SUVs) at all, a system like this wouldn't hurt much more imo.
