Just watched Odyssey. The question is: what could be used as proxys for Myceneian and Trojan armies? Are plans to further expand the Bronze Age range, even in to the "myth" sphere?

I suppose it depends upon what sources you are using to base your Trojan, Myceneian armies on. Is it Hollywood inspired, based on the ancient Greek tales, or archaeological evidence? All three are equally valid (from a wargamer's perspective) but might affect what figures you use. Rapier Miniatures do produce a small Trojan range at 6mm along with some Greek Myths creatures. Might be worth having a look at them to get some ideas.
