Gaming

Warframe is a nice one, at least once you're past the initial learning curve. I'm at the point where I can just zone out and play casually, no need to farm much of anything. There's so much content, so many weapons and frames to unlock, that once you're in the endgame you can really just jump around and passively collect stuff. Plus making your character look cool is something I enjoy doing in games, I can just spend an hour messing with loadouts like that.

Old arcade are always fun too. And Kirby's Pinball Land on my GBC. There's definitely a charm to a lot of them, lots of unique choices being made before things got a little more standardized within each genre.
