I probably should have finished this game long ago, but I wanted to get the “good” ending, and that requires not killing everyone, and this game makes it a lot more fun to kill everyone. It requires patience to sneak around and choke out so many of the things in your way, and I’ve played this in fits and starts because I’m much more direct than that.
There’s also a lot in this game. The levels are enormous and there are books and lore and non-hostile characters all over the place. Much more of the game world is revealed in the texts than ever presented on the surface. Maybe I didn’t connect enough of the dots, but I want more of that world-building because it’s really interesting. It’s a great blend of sci-fi and industrial age.
