Nice idea but I would prefer if producers keep concentrate doing toysoldiers, machinery, and other staff more difficult to make D.I.Y. Especialy considered the usual high cost of these kits.
After have learned the right tricks, materials and techniques I was amazed of how cheap, easy and quick is to do myself buildings fortifications and all this kind of stuff.
For many kinds of buildings it's even quicker than assembly a kit.
With a minimal practice I got excellent results that look more realistic than many commercial kits.
I perpeared a tutorial about it on soldatinionline.it, when it will be pubblished I'll post a message.
