This is an extremely disappointing map pack.
What you can do with these maps is definitely limited compared to City or Grasslands because almost all of them lack any symmetry or at least interesting alternate options for the players on each side when you use them alone, and when you try putting them side-by-side you rapidly realize that CGL made some questionable decisions in how the maps that line up with each other are split up between front and back.
To really use these I feel like you need to have two of the same pack and to be using 4 at once all the time to get interesting terrain options to navigate, which is too much of an ask.
