Despite what many people think/have heard, most places do not have a specific law against doing loops in a roundabout. And when they do it is often a local ordinace(mostly small towns trying to prevent a local car community from driving up and down the main street all night). Although other laws or regulations can apply depending on circumstances.

Things like impeding/obstructing traffic, careless/reckless driving, noise ordinance, etc. But if you’re driving around one in an industrial area at night, the worst you’ll get is probably some accusing questions and a “warning”.

Most of the time they’re just lying about things like this.

Yeah, the amount of industrial machinery being controlled by ancient hardware would baffle a lot of people.

For a comparison people might relate to: There are ATMs running twenty year old versions of Windows XP.

There is some C in the game as well:

It’s 99% written in x86 assembler/machine code (yes, really!), with a small amount of C code used to interface to MS Windows and DirectX.

Yeah, Quake 2 recommended a Pentium 133, and that was released two years earlier(the AMD equivalent was released only a year and a half before the game). It required a Pentium 90 which was three years old, but it didn’t run smooth from what I remember.

That sort of requirement for a major component today would be considered self-sabotage for most non-vr pc games.
