I know this is a pipedream, but I hope behind the scenes this is what they're doing. It's probably impossible to secure the rights from game companies which are no longer in business, but if they're able add third party titles to the Nintendo Switch Online membership, and have it include games up to the Wii U era, that would be a pretty good subscription model.

I think they key would be centering it around a good online multiplayer lobby system to play the multiplayer version of these old games. This is a value add that you don't get via emulation. The current system of needing to be friends first is a big hurdle to play most of these games in NSO.

Also disassociate the name from the console. Don't call it Nintendo Switch Online and call it Nintendo+ or some shit. Have this service be available on all platforms and easy for anyone to use without Nintendo hardware.

But who am I kidding, this is Nintendo, they're not going to do any of this and just sit on their stacks of cash and make The new New Super Mario Bros. exclusively for the Nintendo Switch 2
