Been working on the simulation code for Productive. Interesting thing is, even without the movement rules (all movements are instant right now) the game play almost works. That is, you can take over someone else's unit, you can build the cities, have to manage your resources, etceteras.

Doing something wrong with the scrolling code in the spike rendering test, missing the edge rectangles. Probably an off-by-one error somewhere. Andrew's going to work on the networking tonight so that we can try it across the network. Will need to get optimisation started at some point so that the Pygame renderer works at a reasonable clip on the XOs too.
