I've been pondering of late the subject of game maps and how they can vary quite radically from title to title. Size, content and instancing can all have an impact on a maps accessibility and the way they are perceived. Then there is the issue of individual player tastes and preferences. Those who like to explore will happily spend time attempting to access remote nooks and crannies. Others will quickly become frustrated if there is no direct route to their goal, as with Guild Wars 2: Heart of Thorns. A games genre also has a significant impact upon map design. A FPS or MOBA has different requirements from it virtual environment that an MMO. I'm sure there are far more variables involved in a maps creation. However, I think most gamers seem to inherently know when the developers have got it right.
