Fantastic maze, reminds me of a game I made up as a kid. Reinforcements can add up pretty fast for both sides, so I echo comment about defense/attack strategy.
This map is quite fun for 6-8 players...one must choose wisely on their attack/defense policies. Choosing the correct spot to place reserve units for defensive purposes is very key.
It seems like a good dice start is more important than overall strategy, but that might just be a maze map thing since you can have so much production behind just a couple choke points.
Unlike many type of crossword types, this one is very symmetrical in structure... the layouts are the same in all 4 areas. Good to have a unique board of this type (unique in that the structure is not unique!). The fog is great, and the challenge of finding the right balance between defense and aggression is quite fun. Good for 4-6.
