Don’t even bother trying to get pieces from Hasbro. They don’t care about us A&A players to offer part sets to us & when you ask they just give you the royal run-around. Sorry if I sound too bitter…
I used to play BattleFleet Gothic (other games workshop game), then my friends gave up on it and moved to 40K. Eventually I caved, and bought a 40K army. Since then they’ve moved on to Plain 'ole Warhammer and Mordheim. I’m still trying to convince the buggers to come back to Battlefleet Gothic. I spent hundreds of dollars on my Eldar fleet.
