HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

It looks good, but I lost both times in quick matches. So, even knowing the mechanics, it's not that easy to use. At least, no one has found reliable algorithms for it yet in the World Tournament. And in general, I think this is one of those topics that is better left unexplored. There was already a precedent with the research on morality; after that, the offline players didn't know how to move forward with the new information.
