Heroes of Might and Magic is a series of video games originally created and developed by Jon Van Caneghem through New World Computing. As part of the Might and Magic franchise, the series changed ownership when NWC was acquired by 3DO and again when 3DO closed down and sold the rights to Ubisoft. The games feature turn-based, fantasy-themed conflicts in which players control armies of mythical creatures. The series began in 1995 with the release of the first title. A sixth installment, Might & Magic Heroes VI, was released on October 13, 2011. New World Computing closed after the production of Heroes of Might and Magic IV, and since then the rights to the franchise have been owned by Ubisoft. Nival Interactive developed the first game in the series since the changeover, Heroes of Might and Magic V, with Black Hole Entertainment developing its sequel. The series is directed primarily at the DOS and Windows platforms, with sporadic support for Mac OS over the years. In addition to Windows and Mac platforms, Heroes III was ported to Linux, and GameTap has carried the first four games in the series since 2006. Remakes have also appeared on the Game Boy Color.
