Thanks for the videos!
I've seen the second one, the first one is new.
I've also seen the game Frostpunk and I'm DYING to get my hands on it. It looks like a lot of fun and a preview review showing gameplay really made it look like something I want to spend many hours in!
EDIT:
I got to the end of the first video you linked -- we get a shout out from the creator about putting together the packages for OP1 and OP2 that run on modern hardware. I didn't realize how good it would feel to get acknowledgement especially on a video that's received over 20,000 views.
