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

I also disagree with removing the obelisks. In general, the rule regarding obelisks should be reconsidered. The Grail actually creates a real imbalance only when it is unearthed within the first three weeks (especially if it's on the first week, which is quite possible, for example, on a small map), after that, the opponent should have opportunities to counter it. And after the fifth week, it's usually not about the Grail anymore. But even in the fourth week, digging it up requires some effort. Javdet's option doesn't seem very good to me; you'll have to keep track of the obelisks, which adds extra complexity to the rules.
