I would absolutely love to have maps double the size of the current maps. Many of us like to recreate the immediate surrounding areas adjacent to our zoo projects. When you built your projects in a realistic scale, this becomes a problem. The actual zoo does not have to be a problem, at least in sandbox, as you have the ability to turn off the unrealistic space requirement of the majority of the animals. An option for double the map size would be fantastic. I have often seen here in the forum players request a smaller version of the map as well, so maybe three options? A small map, the current standard size and an extra large version?
