@Anon There are games that while not quite as big a Skyrim are much much more interactive, Deus Ex is a perfect example. Also there's a reason there's a loading screen when transitioning between cells. Like BravoAlphaSix said each cell is rendered seperately to save memory space, for example if you're in the overworld map and enter a Nordic ruin then the overworld is despawned and the ruin is spawned then if you enter another sub area of that ruin the area you were just in is despawned and the new area is spawned. If the entire world was just one big map with no cells then no system would be able to handle it, not even a high-end PC. So no memory is not the issue.
