For what it's worth, most games take place in 'flat' worlds- few replicate any kind of curvature.
Surely this is solid evidence that a Flat Earth counter-resistance conspiracy exists within the video game industry.
Again, reasons for a FE environment in a game summarized for those with short attention spans...
1. Limitations in storage space of the game media.
2. Limitations in system memory of the console and computer systems.
3. Creating a RE environment on the scale of a planet would add nothing to the gaming experience.
4. Programmers take shortcuts, but enhance and exaggerate smaller elements to get their end result.
like FET.
