I was just thinking of creating a map like that, based off of ahli's old traffic simulation map.
Edit: If any terrain guys would like to help me, i could use a 256x256 map with 4 airports, and 4 cities (one at each airport, and in between, Also have them connected with roads), with at least one shop in each city, I'll take care of it from there.
Here is the map I'm working on for this right now. All i've done so far is terrain. (damn you Darl, no template map). If anyone would like to finish the terrain for me that would be great. I'm taking a break from it for now, I'll get back to it sometime today. BTW the map is HOTS dependent.
Here is the map I've been working on so far. I'm not gonna have the time to work on it for the rest of the summer. It's got the terrain layed out, with lines in the airport. And the start of my triggers for a complex road system. It is HOTS dependent, if any of you want to convert it to WOL for others go ahead. HFGL
