The result is kind of cool, but perhaps a bit "out there" if one wants ever to resell the game. And maybe just a bit too "fiddly"....I just drilled each hex vertices using a small bit (1/16") and sized to take the trunks of some nice little wire trees I got on sale at my local hobby shop. I forget the manufacturer of the trees but they are simple twisted wire trees with some clump foliage glued on. But when you stick them into the board surface it gives a fairly good alternative to the woods tiles. (I think this idea would work even better if you laid the gameboard on a piece of blue styrofoam insulation so the trees would hold better in the surface.
I'm still not completely sold on this idea. I just drilled a corner of one of the two Battle Cry boards I own just to experiment with it. I have to give it a few days to see if I really want to drill all of my boards this way. it just seemed to me that if I was painting the figures I should do a little more with the terrain. It kind of warps the boardgame idea...but the effect is pretty good.
I also want to do the full treatment of this idea for my 40mm homecast horse and musket stuff by doing up some layers of boards drilled to H.G. Wells specs. (...and not to mention the new Spencer Smith 42mm 'Little Britons" has got me on full alert... with calculator in hand trying to work out how to afford a classic set of "Little Wars" toys soldiers! (Many thanks to Ross for the link!)
Nothing like some experiments to get the gaming juices flowing!
