I’ve gotten a few emulated titles on Wii and WiiU in the past. I preferred the Virtual Console collection from those consoles. You’d pay a few dollars for the title you wanted and you had it forever. I’m not a fan of the strange bundling of online services + retro gaming with Nintendo Switch Online… not to mention the expansion pack. I just don’t do enough retro gaming to justify it.
As much as I prefer going legit for gaming, if I get a retro craving I’ll probably just set sail on a trusty PC.
