As of this post I have 1624 hours on it. I don't think that's entirely accurate since I've also used the non-Steam version, and I've left it open in the BG quite a lot, something you're probably more likely to do with wide open sandboxes. Just one of a few avenues of letting creative juices flow. With my current computer with more modern components, I can feel like downloading more scenery-heavy parks from the workshop.
I can get sucked in if I have an idea in mind for a custom test chamber, but I can also get lazy. 270 hours as of this post, but it's still above average compared to the rest of my library. I feel the puzzle elements can be used for a variety of creative set-ups, but thinking of how tends to push my brain on the edge of my comfort zone.
Pokemon Puzzle Challenge-
I like those fast-paced puzzle games that play differently each time
well it was, until it finally sunk in that Niantic prioritizes minor text fixes over adding more Johto Pokemon than the ones that hatch from eggs as well as getting colder outside, so I uninstalled it for now to preserve my sanity.
Also pretty much any story-heavy game once I've gotten to the meat of the story and if it has a pile of plot twists and/or one or more characters who are walking spoilers.

How am I so creative? I think taking walks might have something to do with it.
Every single level I will ever make in SMM2 will be easier than Ultra Necrozma.
