Imperium 2nd Edition

I'm a big fan of GDW's space game Imperium. Imperium came out in 1977 about the same time as Star Wars. Gavin, a friend of mine from college, and I played this all the time. I just recently found out that you could get a PDF copy of the 2nd (GDW) edition from Drive Through RPG. (The illustration that they use is from the 1st flatbox edition, which I have, but the rules are from a later edition.) One significant change is that the Imperial player has to pay 2 Glory Points for appeals to the Emperor rather than 1, so that it's harder for the Imperial player to gain the resources he needs to fight the war.
