Earlier quoted context omitted.
Actually 4 was supposed to be a better game than 3, but there was a huge backlash against the introduction of a technologically based faction. They scrapped this idea and the game was rushed out. 3d0 went bankrupt right after.
I had never known they were planning a technology faction for HOMM4, that's interesting to hear. Might and Magic is a fun setting because it's secretly SciFi and you would never know it from the Heroes games as far as I've ever seen. But a bunch of the Might and Magic RPG games start with sword and sorcery and end with laser guns.
That got mostly cut during development and they never went further down that route. Horn of the Abyss is attempting to bring that faction back to life with Forge.
