So you know that the reason is hardware limitation that makes the game limit the number of tiles but somehow you think that demanding less than the maximum number of tiles would not be limited by the same hardware limitations?
It’s 9 tiles. That’s what it is and what it will be. You’re gonna have to accept it. Best you can hope at this point is that they make maps interesting, make different versions of maps so we could use different parts (simply putting the entrance from the highway/starting square in a different point would make maps more re-usable) or, at the very best, that they use the tools we have to allow us to make maps more interesting (I’d take a “map editor” that is nothing more than the terrain editor with nature props (trees, rocks) and a way to change the starting square would be the cherry on top.
