As silly as it sounds to say, the importance of Boatmurdered can't be understated. Boatmurdered was an internet sensation and put Dwarf Fortress on the map; the depth and complexity of the simulation was mind-blowing to read about for the era (and it's still more-or-less unmatched in many ways). Without that there'd be no Infiniminer (and later, no Rimworld, no Factorio), and without that there'd be no Minecraft.
