Wow, great to see all your Romans lined up! I need to get on with digging mine out properly and seeing what I have. Wouldn't it be great of Playmobil did a few klegionaries with a differet base color? Then we could have a Blue legion, green legion etc.
I notice you have your men lined up in 100s, but actually all cohorts after the 1st actually contained 80 legionaries (the 1st containing 160). If you split out the extra men and add them to your third secion you'd have 3 full centuries.
Like you, even now I barely have room to display my Roman army indoors, so I kept my centuires as representative rather than realistic, with 20 men per century plus three officers.
