Quoted from cjmjmm2006:Collecting different things over the years has showed me rarity, for the most part, is desirable amongst the hard core collectors no matter what.
I agree, but in the case of Alien - there is one huge difference...
I own or have owned many rare games and have played all the others - USA Football, Mystery Castle, BBB, TBL, CC, Joust, etc. Every one of those are good games and command a high price because of their rarity - but none of them are phenomenal games IMO. Alien *is* a phenomenal game. My advice to anyone looking to buy is simple - do it sooner rather than later.
