Its not about making the trooper look like the game trooper in the sense that its animated, its about using the parts of the armour that make up the costume. IE. The hand plates, trim around armour, style of helmet.
Your comment Sonnenschein also indicates that the Incinerator Trooper and Stormtrooper Commander should also be a peacura? Seeing that both of those models as well came from the same game, are the exact same model and the only difference is the paint applied to the costume.
I don't see any reason why this variation, like the TKC or Incinerator should not be used? There are 1000 different clones, its just a matter of making the one I want to wear.
and P.S, Sonnenschein, Your opinion matters just as much as everyone else... Your no less special then anyone
