Steam is holding another publisher sale, discounting Square Enix/Eidos titles by 50% through March 26 with a new game or franchise reduced by 75% every day (Tomb Raider today). It's worth noting that Deus Ex: Human Revolution will likely be chosen at some point, making the game about $7.50. Meanwhile, GamersGate bundles Dragon Age: Origins Ultimate Edition and Dragon Age II for $13.58, Amazon has Total War: Shogun 2 for $7.49 (Fall of the Samurai is 33% off at Green Man Gaming), and EA is still offering Batman: Arkham City for $10 if you buy Mass Effect 3 for the full price.
