They created it for Warhammer Fantasy Battles campaigns. I'll use it for that one day but for now I bought two of these sets plus a set of Planetary Empires and built my own map for D&D. And I bought some special river tiles from GW's website.
That's 148 tiles. It's 25" wide by 31" tall. It took me weeks to paint these. Here are the pictures. Click the thumbnails to see bigger images.
This is the overhead shot. There's a snow-capped mountain range to the right, a marsh to the left, a lot of forest in the upper half, and a desert at the bottom. A blue river runs from the mountains.
Here are shots from other angles.
I sculpted a few tiles. There are three big mountain ranges here.
Two forest tiles are taller than the rest. I sculpted them too.
I tried to build a wall and it looks ok. Also, this picture shows the damage the edges of the tiles take when assembling them. The paint gets messed up.
Here's a low-angle shot so you can see how tall my mountains are in comparison to the terrain. About 2" taller.
You have to decide what color to paint the hex edges. You could paint them the same color as the terrain, but I chose to paint them a neutral color. It's a pale gray-green called Rotting Flesh!
