It might be good to produce a short video recorded from a "mock battle" type thing. Pick some historical conflict fitting the time-period(s) and have those folk on each side wear themed, but still unique (to each individual player) gear. Make people think "damn girl, I could get up in that 100 years' war with all my friends(lol)"
In addition, it may be useful when inevitable comparisons to warband come up (I have seen posted on comments that the game appears to be a high-budget warband mod with a few new features) to explain just how different cRPG is from "warband". When the average gamin' joe thinks of Warband, he'll bring to mind single-player mounted bot-slaughtering and rudimentary kingdom management. Yeah, single-player warband can be neat, but I think it could be helpful if people understand just how different the experience (likely neglecting to mention more notable cases of jackassery) of cRPG is from what most people think of as "warband".
