In the wake of Steam's numerous sales throughout the year, it's easy to forget that other PC sales occur. Such is the case with Blizzard's annual sale, which is going on right now and features some of Blizzard's biggest titles. World of Warcraft is discounted to $5. For $10, you can pick up Starcraft II: Wings of Liberty and Startcraft II: Heart of the Swarm, while Diablo III and Diablo III: Reaper of Souls come in at $20. Are any of these titles worth the price? If so, you might want to pick them up while you can. The Blizzard sale is only active through next Tuesday!
