Taking a look back through the Nintendo eShop on the Switch, there's some really great stuff on there, some of which I've already played and some that are entirely new to me.
I've enjoyed revisiting Dragon's Dogma: Dark Arisen. It doesn't reinvent the wheel or add much—if anything—to the original game but it's surprising how little of it feels dated. It also feels and plays pretty well on the Switch.
Another one I've had a blast so far lately is Shakedown: Hawaii. I'm in love with art and animation style. It's amazing how much life pops out of each pixel. There's a million things to do so it definitely scratches that completionist itch.
