Dwarf Fortress is not in the same league as NetHack. Dwarf Fortress is possibly an order of magnitude of leagues above NetHack in complexity, depth, and replayability. While I've probably spent a comparable amount of time playing both games over the years so far (on the order of +80 hours), I expect to spend far more of my life playing Dwarf Fortress as it continues to mature.
