So this is my dream Star Wars arena that I've wanted since the 90's. Geo-Hex desert sets, plus a bunch of scratch build weird forests based on the old WEG illustrations. Built a foam and spackle house, plus a spark plug for the basis of a vaporator. Just like in the old D6 book! Pics cross posted from my army threads to get the table journal started. This will work as a desert very well but if I choose the right stuff to put on it, it can also be a forest or city table. To do this you'd need a Geo-Hex basic set plus a few spare flat tiles to make a flat 3x6 or 3.5x5.5 base, and a single rough hill expansion. Toying with getting a geo-Hex 4x6 flocked felt mat to free up flat tiles to make truly big hills, and/or, to more rapidly setup a table.
