I highly doubt that anyone has not made a game whose systems complexity surpassed the algorithmic hurdle of multiplying three numbers, or two numbers and a constant. I have not previously heard of this person or of their work.

Were it not for HN, I likely wouldn't ever have -- he made two 4/5 games, and sold a quarter of a million copies! This is absolutely a modest success, but this was thirty years ago. He doesn't seem to have published anything since: wikipedia says he started working on Interactive Fiction in 1991, but stopped in 2018 (having released nothing) since "humanity will take centuries to catch up". It seems as if his ego has outstripped his accomplishments.
