Interesting concept Reno, and I see you are going to continue across the flatshaded theme from last years competition. Hopefully you'll have more success than last time, though with the simple nature of the architecture and the new engine that shouldn't be problem.

This sooo reminds me of the board game 'Settlers of Catan'...

Anyway, nice style, though I'm wondering how you will turn this into a playable DM map that's still interesting enough. The hexagon theme alone lacks a bit character to make up a full map, I think.
Especially that unlit, cartoony feel makes the map look very un-Sourcy, in a bad way I think. It's too simple to become really interesting right now.

Reminds me a lot of Haste's "Stolatene Mine" for Quake 3 ... http://www.planetquake.com/nunuk/geocomp2maphaste.htm

Nicely done so far!

That looks cool. which remeinds me, I should get started on a contest map.
