This is the terrain board I have (Urban Grounds, second one down):
Battle Grounds
The set is all painted and complete.
I also have Streets of Ledgend and the Armoury (Terrain X) from here:
Worldworks
I hve only printed and assembled a few test pieces of this though.
I too like a multi-age set of rules for skirmish. Maybe we could trial a set next session? (I favour Chain Reaction 3, I know Kevin has a copy of those too).
