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?
It’s not about the size, but more about density of meaningful content. I like Elden Ring because every nook and cranny feels worth exploring. It’s the game that dares to hide optional areas behind optional areas, all with their own unique enemies and bosses.
On the other hand, taking Elden Ring as an example again, the mini dungeons were too repetitive. The first time visiting a catacomb is exciting, but it turns into quite a chore after the third time and onwards. You’ve already seen it all. Same thing with the dragon battles.
I think Elden Ring overall strikes a good balance with amount of surprises per square meter.
There was one maze type catacomb with teleporting chests that was like a breathe of fresh air.
