The user interface is terrible, the frame rate is awful, the game designers force you to grind the same repetitive task over and over again and build in barriers of frustration into the game to slow your progress.
the game loops equate to pressing a button for 26 hours over and over again, to unlock the next module, before pressing a different button for another 30 hours for the next one, and somehow this is "gameplay"
just a terrible and awful DLC needs another few years of work
