How Much is Too Much?
One issue might be that open worlds in games have gotten to be bigger and bigger in recent years. The size of the map has come to be almost equated with depth of content, and new games often seek to make their maps as large as possible to impress players. But does there come a point at which there is too much land to explore, leaving a lot of it untouched? Certainly, we saw with the recent Red Dead Redemption 2 that the sheer size and level of (sometimes mundane) detail could wear players down and kill the fun.
