I'll add Dungeon Crawl: Stone Soup to the list of games that might appeal to the type of person who reads HN. (It's a rouge-like, somewhat similar to NetHack, but with much less requirements on inane trivia than NetHack.) (I will also add that Factorio, Minecraft, Dwarf Fortress, and OpenTTD, mentioned by sibling comments, are all excellent. Factorio was definitely worth the cost IMO. I think the only other long-term addiction I've had not mentioned here is Zandronum, a modern Doom port.)
