Unlike tylermo, I'm not 15mm averse, although the humans in the official range are a little "oddly proportioned", IMO -- nothing to stop me using my SG2 or Laserburn minis for games of Battlestations!
Anyway, thanks for the review, Matt. This is a supplement that I've been awaiting eagerly ever since I saw it in the Battlestations release schedule. I've wanted a space emergency rescue game for a couple of years now.
One question (for now): does Pax Galacticum require the first supplement at all? Or is it completely stand alone (apart from the main rules)?
