For me, the ideal Heroes game would have:
1. All the new features and capabilities from Heroes 3.58f: WoG (i.e., "heroes on the battlefield" (commanders), experience for creatures, and ERM scripts, new artifacts, creatures, and many other new features).
2. An interface and design in the style of Heroes 3.58f: WoG with elements from Heroes 4.
3. Graphics at the level of Heroes 4.
4. Soundtracks from Heroes 3.58f: WoG and Heroes 4.
5. The old Might and Magic universe.
Based on the above parameters, a mod for Heroes 4 could be created. Add music from WoG, make corresponding changes to the design and interface, implement features from Heroes 3.58f: WoG, thereby returning game elements from Heroes 3, and create Campaigns in the old, good M&M universe. Also, for me, an option without point 3 is acceptable; that is, the graphics can remain as in WoG, and then the "ideal Heroes" can be implemented even easier by adding music from Heroes 4 and some gameplay elements from there (the same "WoG settings"), as well as in terms of the interface (heroes on the battlefield are not needed, as they are perfectly replaced by commanders). "Ideal Heroes" without point 3 can be quite easily implemented with a new patch for WoG. From everything I have written, it is easy to guess that WoG, especially the latest version 3.58f, is the closest to my "ideal Heroes".
