I've finished the Car Wars map that I posted as a work-in-progress here. I'm really pleased with how it turned out.
I got a couple of other ideas whilst drawing it, but it might be a few weeks before I get time to draw any of them. I also thought it would be cool to print some paper with the grey shading of the old Car Wars maps so that cut out buildings drawn on the white sheets can be placed on it. I'll add that to my long list of future mapping sheets.
The blank mapping sheets can be found here.
