Here are the changes:
- I've taken on board most of the suggestions; I've opened up the mountains between San Luis and Tamaulipas to make that area not so linear.
- The mountains between Michoacan and Edo. Mex. have similarly been removed to open up the Central region a little more.
- I've removed the Baja +1 bonus, and bumped Noroeste back up to 4, although I could be persuaded to drop it back down to three as it feels like it should be 3.5!
- Graphically, I've made the central area more yellow, and to be honest I preferred it red. The Eagle on the Mexico flag is much more brown than yellow, but brown looked even worse (and too similar to the unplayable areas).
- I've taken off the texture from the land, and actually like the sleek modern look it gives the map.
- As for the port icons, I really don't want to switch to an anchor; the icon I've designed doubles up really nicely as an army circle, and (in my opinion) fits the map quite nicely.
