Great Santi... in my country some WW1 group builds started already... but mainly airplanes.
I hope here, in our group build, figures will prevail... that doesn't mean you can't build a tank or nice airplane.
At least 2-3 more participants and we 'll have minimum for start it. I think we'll have open this discussion for couple of weeks. 6 months is enough to buy some figures and finish project.
