US citizen here, all the world maps the teachers had on the walls in school placed the North American continent in the top left, with the Prime Meridian running along the center or very close to it (sometimes things were adjusted a bit so that Siberia would be entirely on the right side of the map instead of straddling both edges). North American-centric world maps might very occasionally show up, but only in contexts where it made more sense to divide Eurasia than the Pacific.
Not the person you asked, but one game I had problems with on Steam that I did not on GOG was the OG Riven. It was still playable, but the various animations associated with pressing buttons and suchlike were completely broken. Very rare experience though and I have played many retro games on Steam.
