Thanks for helping me look at the evidence! Maybe you're right. Do you want to pick another two or three random games from that list and figure out what language they're written in? Or figure out what MK3 was written in? I was trying but then I ran out of time while writing my comment.

I don't think RollerCoaster Tycoon is a good piece of evidence because it's famous largely for being written in assembly at a time when most games had already abandoned it.

(Sadly, I don't think it would be odd at all to ignore the evidence, but I aspire to better than that.)
