The point about 'getting used' to poor features, or indeed even bugs, applies not just to video games but any type of software you work on for a long time (especially personal projects, where you don't have a QA team).

This will no doubt be familiar to many of us on HN.

That's my understanding of what "Hallway usability testing" from the classic 'Joel Test' meant. Having fresh eyes on a thing vs. the same people 'testing' it forever.

There's a similar phenomenon when looking at an electronic todo list. You get used to reading it top-to-bottom and skipping over certain uncompleted items every time. It's nice if there is a feature to randomise the order of the list, to give you a jolt into properly considering each item individually again.
