Once I made all the infrastructure to create engines, I've discovered they are less powerful than a steam engine, that requires less than 1/4th the infrastructure to run. It's far easier to run shafts all over than pipe gas where it's needed as well. Dramatically so.
It just, feels like I've wasted a lot of time for absolutely no reason except to see what this mod's engines have to offer.
I understand, it's an interesting process, and it was fun to do. But the payoff, there just isn't one at all.
