Here, a truly small battlefield can be found in the first Heroes game (4x4)! There, you really don't have much room to maneuver. But in the 5th game, I find it quite suitable, especially the ability to arrange troops before each battle (regardless of the Tactics skill). As for the 4th game, the battlefield is large and realistic, but it's not always convenient to play on – there are no movement shadows or cursor shadows, and the slow-moving troops take too long to go around obstacles.
