The demo was great, the importing system was really useful and surprisingly easy to understand and use. Although i didn't know what the blue and green arrows meant? were they linked to supply and demand maybe?

Also, is there a way you can paint the terrain in Tropico 4? Because it always bugs me when i've built two buildings side by side ad theres a tiny gap of grass through the paving, or between the building and the road etc. Also, when i demolished a building the grey paving was left behind, does that stay there forever? or can i erase it or maybe paint some grass on it??
