The best part is the extreme amount of customizability of the set. There are several textures to choose from (concrete, brick, stone, wood of various colors), then a few effects (smoke, bullet damage, etc). With all the shapes, textures and effects, there are many ruined wall combinations.

I would say that this set requires moderate cardstock modelling skills. The tricky part is getting the front and back parts to match, so there are no ragged lines or black-lining work to hide the white cut marks. This is especially important for the windows. I usually cut the piece out with some margin, fold, glue, then trim to the marked lines. This technique does not work in this case, because of the assembly order. Therefore, I had to dry-fit the interior and trim up the windows so they did not look misaligned.

Overall, this kit is a great buy for it ease of building, number of combinations, good graphics and basic game utility. I've built several DG kits and there is a good, consistent thought to his designs (not a builders nightmare) as well as color, textures and choice. I hope DG makes the multi-layered PDFs a standard part of every product.
