A little while ago I picked up a 10mm ECW starter kit from Pendraken - enough figs for a few regiments of pike and shot, a few cavalry, and some artillery. I painted a regiment of foot over the weekend and here they are:
I like them - and I like the small footprint. They are based on an 80mm frontage.
The picture below compares them with a similar sized (in figs) unit of 28mm Warlord troops which have a frontage of 180mm:
As much as I enjoy painting 28s - and they sure look great - the problem with them for ECW is the size of each unit. I can only really play on a 6 x 4 table - with each regiment taking up more than half a foot of frontage - there is only so many units I can get on the field before it just gets too crowded.
Now my decision is whether I take the plunge and go for 10mm in a serious way... but I have three complete 28mm ECW armies on the shelf at home now.
