Maps in R2DA come in all shapes and sizes. This is a comprehensive ranking on the size of the maps.
The Map Size is defined as the total area playable if all the maps are super-imposed on each other. Only the area from a bird's eye view is counted; not the total area from a vertical viewpoint. Water is only counted towards the size of a map if it is safe. Terrain is also only counted if it is safe (for example, it doesn't trip you, it isn't lava and it doesn't kill).
