I have to admit, from the first time I saw Stoeztl's stuff I was impressed. Unfortunatly I had already sunk too much money, paper, ink and time with World works games and Microtactix terrain.
WWG's stuff is quite and undertaking. I takes time and dedication to get your monies worth out of their products, but boy are they gorgeous.
Microtactix on the other hand is what I have spent most of my and the kids time on as it is very simple and quick to build.
