I disagree about the distance between the two islands being too far. I love this map for single player mission design. The airport island is great for base design, and the main island with large forests/base/towns is awesome.
I have been looking for a map like this for a while. This map has prompted me to write scripts for heli-extractions, cargo drops etc. (Heli script posted on beta-script forum, built and tested on visnorsk.)
Also, if the player (based on airport island ) attacks the larger island, you really become dependent on air forces, which is a new challenge, especially if u load the main island with lots of AA
anyway, great island, thanks.
