Garfield Kart: Furious Racing
Got in a few more races and achievements before it did actually leave the free-with-Prime tier on Luna. And then I tried to find a replacement...

Smurfs Kart
Very similar on the surface, but a few changes to controls and difficulty made it much less satisfying. I did a few races, but I'm not sure I'll be going back.

Trackmania
A different kind of racing game — still a bit wacky, definitely not a sim (there's also a monster truck game on Luna that sounded altogether too serious), but not a kart racer either. I didn't care for the way it's not always clear where you should drive, and if you go wrong it will just let you wander around, which is irritatingly pointless. Also not really built for the levels of input lag you get on cloud gaming.

Oh well. At least it doesn't cost me anything to try these. Imagine if I got a Switch 2 right now and hated Mario Kart...
