I got Drum N Fun on it's own without the drum peripheral, and it's really a lot of fun. Motion controls are crap but playing with the button are pretty good. Some of the J Pop tracks here are insanely catchy.
I am, I’ve put about 6-7 hours into it so far and I really like it. Tons of things to do with different events and quests to complete, I understand they have a lot of online features as well like raids but I don’t have an online sub at the mo.
Splatoon 2 is pretty good online. They've altered the older maps in some ways. More interactive elements to the stages added, like zipl lines and sponge cubes. I really like what they've done with some of them.
I've barely touched my Switch since I bought it, I had a brief time of a few months but that's it. My little girl loves the thing though, she's up to over 600 moons in Mario Odyssey and is currently hooked on Breathe of the Wild, she plays it all the way home in car (which is usually over an hour per day - I have a car charger) and then just before bed time. She's done and found things in BoTW that I didn't know exist.
