Lord of Ultima, a real time browser game I wrote about a few days ago, can be tricky when it comes to setting up your cities. Whether you're going for a resource city, gold city, army, or whatever, it can be hard to get the 'lay of the land' and organize things in a way that maximizes your total input.
A free ap that I got from an alliance mate helps you to see your overall city, and plan for maximum prosperity:
The flash city planner allows you to arrange resources on the map to mimic the layout of your particular city. You then can arrange (and rearrange) buildings and view the resources you would acquire. (It bases numbers off of level 10 buildings.)
