RTF is a global modification that replaces all towns in the game.

The main thing I dislike about Heroes is the presence of the so-called "final battle," which is often the only instance of interaction between players, as the entire game leading up to the final battle is just a tedious grind through neutral creatures (which you can do in single-player without worrying about playing online), and the entire game after the final battle simply doesn't exist.
To turn Heroes into a decent strategy game, it's necessary to increase the importance of territory control, encourage players to have multiple armies, and significantly reduce the number of neutral armies so that players don't focus on boring, monotonous battles with mobs, but instead fight against other players.
This would require either creating maps manually or modifying the map generator – maps should have a minimum number of neutral units, the number of cities on maps should be significantly increased, and the city development schemes should be edited.
Also, something needs to be done about the heroes themselves – losing your main hero often means defeat, so at the very least, the "Shackles of War" artifact should be banned, or the losing hero should be sent to the tavern of the winning player so that they can be hired immediately.
Victory over a player should mean depriving them of all their troops and cities, not winning the "final battle," and losing the "final battle" should not deprive you of your overall chances of winning.
