The best of the series. 6

14 years after its release, this episode in the long series of Heroes of might and magic rest I think the most complete. With extensions, you left for hundreds of hours of play. The challenge is to go in combat, tactics too. Graphics side, it's pretty even now, but rush to the Internet to retrieve the HD patch (HoMM 3 HD), you can display it in any resolution (handy for the 16 / 10th screen Other large screens).
If you had to keep only one of this series, this would be it.
