Of course, my first game using the full version was as Jacksonville in the US Florida scenario. My basic strategy was to hold back and let things fall into place.
I concentrated on slowly building my military (6 units at a time at two bases), improving social spending to recommended levels, and balancing my resources. I was initially having some problems producing enough electricity, so I built an additional coal power plant. (in a related issue, the coal power plant around Jacksonville should be located at X:070 Y:014...I can see it from my house).
As soon as the power plant was done, I was having raw materials shortages. Question: Is there a priority you can assign so that your advisor will buy enough raw materials to clear a shortage? Either way, my budget was growing.
About 8 months into the game, Central Florida declared war on me. I mobilized all of my troops and eventually made my way to Tampa, and eliminated them.
About a week later, South Florida declared war on me. I sent my Navy to shell them from the water (having the 2nd largest Navy base on the East Coast helps!) and eventually took over the entire state. That's what they get for declaring war on me!
Next: US Southeast as Florida.
Oh, and the game is super-fun. Bonus! Just make sure you speed up the default speeds or some parts can get boooooooring.
