In lieu of video after video of people asking if Nintendo Switch Online is worth it (it is), I'll just tell you that they just added five more games. The Game boy app got Donkey Kong Land, and Donkey Kong Land 2. These are just as good as Donkey Kong Country, and as hard as their predecessors. You can play these if you're just doing the regular tier Nintendo Switch Online plan, which is $20 a year.
The NSO with Expansion pack sees three more Sega Genesis games come, and they're out of nowhere. Shortly after Sega started removing their classics from online storefronts, The Genesis app just got updated with the side scrolling sequel ToeJam and Earl: Panic on Funkatron, the amazing action adventure shooter Vectorman, and Mercs, which is one of my favorite run and gun games from the arcades. We'll give them a play through here soon, but for now, make sure you update your apps.
