I likes 1/72 plastic figures because of its DESIGN, single piece design but look naturally, suclpting and pose, more important the mould! Too many WW2 German in the market, Bored? I'll buy Again, if the Design look Good; less popular subject? I'll buy it also, if the design look good.
I am of the same opinion. Any way, late republican Rome I think it was a period as exciting, or more, than the imperial period. With a state in constant evolution and growing expansion, the Roman armies fought against multiple nationalities at the same time, in different fronts and territories, not to mention their internal problems (slave revolts) and their own civil wars.
A good design of figures of that time in the line that strelets are working, would be very attractive for many of us.
