My Nintendo Switch wouldn't go online, so I called customer service, and they changed a setting on my computer, and now it works. They were very friendly and fast in helping me. I had to be online because I have a code for Super Mario Odyssey instead of a physical copy.
Unsurprisingly, the game looks and sounds great. There are plenty of cool new moves and characters to control/inhabit, including a dinosaur and a frog (not the frog suit from Super Mario Bros. 3). The much-lauded cap maneuvers work great (the variety of uses shows typical Nintendo inventiveness), and the 2D scenes are a nice blast from the past. The game is a little on the easy side, though, at least so far, but I’m having a blast.
