To be honest, the parts are at the practical limits of moulding, with some of the larger bits being slightly, but noticeably warped. It's fair to say Games Workshop have mastered this technique - and although it's an admirable start, Warlord games have a way to go.
Although the parts are modular, in so far as they are not specifically fixed in set up, they really only work in a limited number of ways. The farmhouse itself is more or less a standard layout.
The US infantry give a sense of scale, it isn't massive, but it's a reasonable size. The model could be expanded with the smaller parts of course, but these mainly serve to make the footprint of a second building:
The bases were part of the basic assembly and sanded before undercoating the models. Therefore the brown base colour allowed them to be finished with minutes of drybrushing and a layer of flock.
Overall the models look great finished, and probably justify the normal £15 price tag - if you are in the market for precisely this model. Personally I prefer it to the MDF kits I did a few months back, but on the other hand there really is only this model so choice is limited. I wouldn't want another one!
