There are already some huge maps out there, Just Cause 2 and 3 both have maps at around 1000km2, and those games are beloved by their players. But if the next Cyberpunk game was announced with Night City now being the size of an actual large metropolis, say like New York, would you say that’s too big? What determines what “too big” is?
Measuring size alone is meaningless, as gameplay affects perceived size, and density of meaningful content in relation affects the experience.
Size should match content.
Skyrim is canonically pretty close to the size and shape of Estonia, but in game it’s very small. If the game’s content was spread out to the “real” size, it would feel completely barren.
The map in Deus Ex MD was quite small, just a couple tiny districts, but it punched way above its size because it was so dense in detail.
Agree. If you could go into every single store, house, nook and cranny of Cyberpunk 2077, and talk to all the NPCs, it would feel absolutely humongous. Gameplay significantly affects perceived size.
