Speaking of Aliens
tie-ins, we did have a reference to "Acheron" in A Time to Sow
, in the context of terraforming. For those who don't know, Acheron was the name given to planet otherwise known as "LV-426" (which was being terraformed during the events of the film) in Alan Dean Foster's novelization of Aliens
as well as earlier versions of the screenplay.
I put in the reference mostly just to see if anyone would catch it....
