Hello! I just recently was given an Imperial Assault boxed set and have been reading through it. I'm particularly interested in campaign mode, which from the description seems a lot like HeroQuest from when I was a kid, just with Star Wars. Which sounds awesome. I'm going for an L2P session at my local game store this week and I'm stoked.
One thing I'm curious about, though: I understand how villain packs will be used in campaign mode, since the GM/Imp will use them. Are Ally packs useful? From what I can tell they do not seem to include extra heroes like the core set and Return to Hoth have, so I don't know if they would have a great deal of utility in campaign mode.
This is probably something answered in the books that I just glazed over by accident, so I apologize in advance.
