There are a lot more twists and turn that can happen. Like work safety is a thing now and building the generator comes in multiple phases and shit happens during construction.
You have to make secondary resources to build the generator as well. To make all of this work you have to balance your work force. You can order people from main land or send back people to have less people to feed. There are milestones to hit with the construction that you can fail and lose. Then there is this whole labor rule book, unions and etc opens up later that makes things even more complicated and engineers and workers are at each others throat. There is a lot more depth to this scenario than anything before. A lot more bureaucratic instead of just surviving cold.
Then freezing starts on top and it get really exciting. I think it is a lot more interesting than anything before. It was too basic before and I feel this is the where the game really reaching its potential. It feels very fresh imo. Even on normal settings, it is tough. I failed three times so far lol. The good part is that you can tell how you fucked it up and want to go again.
