I think you get that kind of potential to get stuck on inconsequential details in any design. It happens in video game design of course, but also board game design, and graphic design, and software design in general, among many other fields. Most general design guides encourage iteration and refinement, and when it comes to game design specifically that comes across as the push for frequent prototypes and playtests so you can refine the mechanics. (In the software world it often comes across as the "minimum viable product" concept.) I think people who get stuck on details in ways like you mentioned are people who never learned this, whether self taught or formally educated, or they're forgetting those tenets of design.
