Super Mario Odyssey. It’s mostly extremely fun, controls well, with only occasional camera angles and poor checkpointing infuriation lighting its copybook.

I love this video. The escalating insanity is wonderful. I once got the Harder Drives music stuck in my head for about 2 days straight.

The Curse of the Golden Idol is a detective-puzzle game that is easily played one handed, is cheap, and is great.

Invisible Inc is like a stealthy XCOM (which I see on your profile), and again, easily played one handed.
