There are a lot of Game of Thrones maps on Warlight, and I feel this one doesn't take enough inspiration from the others. It's good to be unique, and the different format is interesting, but what does this map have that the others don't? The ports are illogical, plus there are spelling errors like "Casterl rock" and "Sanderstone" Fixing these and reworking the ports might bring this map up to par with some of the others. ATM, 2/5.
Step 1 - Conquer the North Step 2 - Make a sandwich Step 3 - Victory
While the compact size of the map is nice, there are far too few connections and whoever wins the North will almost inevitably win.
For more balance, I recommend additional connections between Dorne and the Stormlands (Boneway), Tarth and Mistwood, Dragonstone and Duskendale, the Westerlands and the Riverlands, possibly White Harbor and Strongsong and certainly Essos and Westeros as a whole.
