My impression is that many folks on LAF (me included) are basing their fantasy conversions on kit bashing hard plastic figures. Knight-Commander Tyr’s threads are great examples, but there are lots more. By mixing plastic historical figures, such as Saxons by Victrix or War of the Roses by Perry Miniatures, with fantasy parts made by Fireforge or Northstar, they are getting great results. The Oathmark and Frostgrave boxes have so many surplus bits on each sprue, you can make the figures up as designed and still kit bash a dozen or more historical bodies with each box.
It is almost as if the sheer number of plastic kits available that are suitable for fantasy conversions makes resin bits like Anvil’s sci-fi lines redundant for fantasy gaming. That said, if someone started manufacturing an extensive range of fantasy bits, I would probably buy those as well!
