There may not be a ton of deals around this weekend, but the handful that are available seem pretty solid. Steam offers a Hitman bundle for $15 that includes Absolution as well as a GTA franchise pack for $12.49, Amazon already has 33% off SimCity ($39.99) along with XCOM for $25 and Dark Souls for $15, while GamersGate is the latest distributor to offer Borderlands for $20. It's also worth mentioning both the Humble Mobile Bundle and the Humble Weekly Sale, the latter of which provides four THQ titles including Darksiders II for about $7.
