You bought the EP anyways didnt you (or am I thinking of the wrong person?!).
I don't know about F1ach, but I bought both the EP (signed!) and a t-shirt.
As for the promotion idea: have someone capable make a mod for Skyrim, having the band members give a virtual concert of one or a couple tracks (on request by the player so as to not get repetitive) while portrayed as some of the nine divines or Daedra princes, depending on which divine/daedra personality fits best with each band member, similar to L90ETC
from Warcraft 3 and WoW. Record it and put on Youtube for those without the game.
Also, um... the only game from the bundle I don't yet have is Brutal Legend, and I'm waiting for that one to appear on GOG, so I'd prefer the prize to go to someone who have not yet experienced most of the included games.
