With their wallet-wrenching holiday promotions just around the corner, digital distributors seem to be playing it stingy this weekend, serving up relatively few eye-catching deals and many repeats. Of note, you'll find a pack of both Prototype titles and Saints Row: The Third for $10 each at Amazon, Grand Theft Auto IV Complete Edition for $7.49 at GameStop, Orcs Must Die! 2 for $7.48 at GamersGate, Binary Domain for $9.99 and Space Marine for $7.49 at Get Games, and 50-80% off assorted indie titles at GameFly. Oh, and The Humble Bundle has added five more games to its latest pay-what-you-will event.
