It has arrived.
Apparently I was incorrect as to the dating. The Companions version I originally had was a later, 1985, version of the game rules, and FASA's was the original in 1982.
That said, sadly, I prefer The Companions version better. TC version had photographs instead of sketchy line drawings, and was better thought/laid-out overall.
In any case, I will be digging into this and my Victory Games' (and MISSION) soon after I put the wrap on the beta .pdf.
Speaking of which: Back to work.
