One thing I really don't understand would be the ergonomics of game dev. I mean, I guess it's just an isometric drawing library, and routines for each object (though this obviously isn't OOP game Dev). But like, for example, he talks about simulating the physics of the roller coasters. I get that, and I think I could figure that out in assembly. But, in my head, connecting the dots from simulating the physics to drawing it on the screen is a huge leap. But yeah, having years of background on using assembler for game Dev would obviously be a big part of that equation.
