Not a big Star Wars fan? No worries, because Steam is also slashing 50% off the Lucasarts Adventure Pack, a collection of four classic adventure titles: Indiana Jones and the Fate of Atlantis, Indiana Jones and the Last Crusade, LOOM and The Dig. All four of these titles are Steam Play compatible and will run on your Mac. You can get 'em for $5, only a little more than a buck a game. That's a pretty damn good deal, if you ask us.
