yeah I see what you mean. They could work for an early iron age/stone henge type setting too.
Re BTD, I think they a great value for money, so long as you are not in a hurry. I use them for my VBCW army a lot, as they have a nice range of partizans, at less that 50% the cost of Musketeer and Artizan (although in trueth, both Artizan and Musketeer are better sculpted, and tend to arive on time)
