You should absolutely play Might & Magic: Clash of Heroes. It's one of Capybara's best games and among my favorite puzzle titles of the 2000s. But, don't get it just yet -- it's going to be free next week as part of Microsoft's Games with Gold program. The promotion will run from October 1 through Oct. 15 for Xbox Live Gold members.
There's also half-price discounts on XCOM, Borderlands, and BioShock 2 DLC this week, while we're on the topic of sales. Follow the link below for the full schedule.
