no laws on ceres.... just cops.
what can change the nature of a man?
I thought the alien sheets were a different size. About 1mm wider or narrower from the older version to the newer.
I have the 2008 version with all of the expansions (from various printings) and can confirm that some of the alien cards are slightly smaller. Doesn't change gameplay a bit, since you select your alien from the flare card anyway.
