The “‘modern’ development stack” we used at my school when I was in a CS program was C++98 or something, compiled using gcc directly. This was in the last decade. It technically wasn’t C!
But we did use C in my computer engineering classes so I guess they technically did teach it. I feel very fortunate that I haven’t needed to use it since then.
I made the mistake of starting Frostpunk (1) since I saw that 2 released. It’s an incredibly well-made game. The art style is beautiful, the game is intense, there is a lot of emotion, and it does its one thing just so well. Unlike a lot of modern games these days, Frostpunk wants you to lose, which is fitting for its setting. It sees that you’re behind, then kicks you in the shins for good measure rather than lending a helping hand. I’ve lost so many hours of my time to this game in the past week.
I’ve read that Frostpunk 2 is a completely different game. That one might be next on my list if I get to it before Factorio updates and the expansion for it comes out.
