Steam has had some great sales lately, with Civilization IV plus all of its expansions on sale. Now another strategy title is up for grabs at an insanely affordable price. Tropico 3 is on sale this week on Steam for 75% off its original price, which brings it down to $7.50. If you've even been remotely interested in this tropical island empire-building sim, now would be a good time to grab it.

Also of note is that the version you'll get is the Steam Special Edition, which comes with some extra goodies like avatar costumes, accessories and two extra maps. Go get it while the gettin' is good!
