“Heroes of Might and Magic V: Tribes of the East”

By the way, even though the fourth game had a different idea, it was a good one... it just had too few units... and that's why people often speak negatively about it.

There were enough units in the fourth game. They could be summoned from the air. The idea of upgrading doesn't fit the spirit of the Heroes series. Although, if everything is done well, then maybe something good will come out of it.
Maybe they should team up with the developers of Disciples 3? They also introduced movement around the battlefield!
