I have yet to actually purchase an online membership for the Nintendo Switch. I've used the trial periods a couple times for a couple things I needed in a couple games, but for the most part, I'm not impressed with the approach here. I get Microsoft and Sony charge services for their systems, Nintendo didn't need to do that though, but that's old wounds at this point, I'd say the worst offender is the service for these older games. You can't buy and play them offline. What the hell is the point of all this? If the power goes out, the internet goes out, travel to some location where I don't have access to Wi-Fi (even if I did it's stupid to use public Wi-Fi due to security reasons), I have no means of launching and playing these titles, they just sit under an install with a generic home menu icon, being paperweight.
I'll never understand the appeal a lot of folks have for this service. You literally pay to access the games, required to be online just to launch the software, knowing good and well it's going to die and you can't even play the games when the system support ends entirely. Of course everyone will scream "just pirate everything." Sure, but that doesn't fix the issue, that just works around it.
