I think I would put Super Mario Maker 1 and 2 here. At least, the online run part. The course editor is fantastic, and if you know some good builders or have a way to find curated courses. it’s great.

However despite how much I’d like to be able to jump into a hundred-course run of Mario platforming (believe me, I would), it’s almost entirely shit. Not even entertaining shit most of the time. It’s either absurd enemy spam, empty courses, trap pipes/doors that lead to either instant deaths or inescapable dead-ends, invisible blocks over pits to trip you when you jump…

And a favourite of mine, the course that would be almost impossible except there’s an invisible secret shortcut to the end right at the beginning. The infamous “dev door”. Because you have to be able to complete your course before you upload it, and the worst kind of trolls obviously don’t want to engage with their own crap.
