Ending a dry spell on digital discounts, EA has cut 50% off virtually its entire Origin catalog as part of a weeklong spring sale. Before you check: Mass Effect 3 isn't reduced, but if you buy the game at full price you'll get Batman: Arkham City for $10. Meanwhile, GameStop has 50% off The Darkness II (barely a month old), Rage and both Dead Rising 2 titles, GameFly has Saints Row: The Third for $22.99, Amazon has a 50% off, buy-one-get-one promo on classic Ubisoft titles and GamersGate has big savings on the D&D franchise.
