If you have a better opinion, please let me know.
Other maps are already familiar maps, so I studied only SimCity on polypoid, Eclipse, and Reap the Storm.
I hope my research will help you.
1. Eclipse simcity
2. Polypoid simcity
3. Reap the Storm
Top right 1
Top right 2
The Reap the Storm is a very unfriendly map.
In particular, the top right may cause zergling passes on the position of the gate. ex) It's only built on one block, but Zergling passes.
So I did a lot of simcity research on the top right position,
I concluded that these two simcity are the best simcity that zergling does not pass.
