Fucking DQ9 did this.
First of all, we had a shitty satellite internet connection so my DS couldn't connect to the thing, because it wasn't a router. That meant no online, so I only got maybe 40% of the postgame shit and severely limited stuff, including fewer classes
Secondly, Nintendo's online services has at least 4-6 fucking services and accounts and I can't keep track of them all so I don't bother, and in addition the UI for it on a console is slow and clunky as fuck.
Finally, the content was time gated so you'd have to connect to the update server weekly for 28 weeks to get all the stuff. Guess what? It's literally one byte of data that's set on your save file that determines what content you have access to, and the game is literally impossible to 100% now without cheating because you require to connect to a server that doesn't exist any more
