I am of the opinion that every POTF2 and up playset were half-assed. The only reason Mustafar worked for me was it was for Starcom. Though I can't figure out what you can attach to the walkway near the door?
I am looking into the Hoth Battle sets for my Clone Outpost, only for the turrets, but I have yet to see what they are like.
BTW, Owens work is awesome. It is ashamed that more people cannot own items like that.
