"Diary of a spaceport janitor" may not be a poverty sim, and looks from the color choices alone far from one, but it does capture a certain mood; a common feeling produced by the 'poverty wage in a bustling hub of wealth' life.

Being a game, it's also an interesting take on exploring NPCs as a subject in games in a rather humanizing way, rarely do games treat them as having interior lives at all, or why far-out space fantasy still reproduces menial labor of our day without question.
