I don't like everything GW has done with LOTR, nor was I totally sold on some of Peter Jackson's splat horror inspired imagery either. So I prefer to use historicals to represent many of the men of Middle Earth. For my 'wildmen', I decided to do something more like the way they looked in the excellent MERP.
I've gone with Wargames Factory Gauls. The upside is always that I can use these for historicals too. I don't think I could ever be a 'warband' army player in ancients games but the Camillan (aka Polybian) Romans in the very cool Impetus system actually have line-replacement and in generally look much more interesting than how they looked in the incredibly dry FOG. The last thing that someone always seems to ask for in an ancients set is to represent Cannae but I'm not quite sure that the Impetus rules can manage that (though some of the Impetus fans who come here may correct me). Gauls (a WOTR base is 'close' enough to 28mm Impetus basing) could always fight alongside Camillan legions and I decided to make them a little more colourful than originally planned.
I'm not sure if the striking Gallic look is quite right. However, I like the way they came out.
