Who could say, that this game would be still alive? And yet, it's.
It does live and prosper, parting not only in "Limited Edition at Gog" but also bashing in continuous modding support to be playable, enjoyable, comfortable and getting some extra love from the fans.
There are several famous modifications:
- M&M Merge678 - Playing all these games in one go with MM8 engine. Collaborative work. See the thread and the links.
- Chaos Conspiracy Redone Enhanced - Based on the original "The Chaos Conspiracy" by Big Daddy Jim, now being cherrished by DaveHer.
- Open Enroth Project
- Immersion Mod - Music Modification
Where you can explore and check various links to other projects. As there's more of it. 
To rephrase from our past:
Introduction, by Vox Clamant
Might and Magic VI is a classic. Perhaps more than any other, certainly more than MM7 and MM8, it is a very non-linear campaign with a lot of flexibility in how you play it. It also seems to have key quests spread over a much wider area leading to a real premium of spells like Town Portal. Indeed, for the first third of the game until you are at a level where you can know the Town Portal spell, one of the two NPCs you will find early on who have that skill are critical.
In the Mandate of Heaven, King Roland has locked himself in his castle, with hordes of demons infesting the land, and a well-hidden traitor thwarting every plan to regain control of the lands. The only hope is that a small band of adventurers from the town of New Scorpigal can accomplish where the great heroes of the land have failed. You must somehow enter The Hive -- a terrible place swarming with demons and worse! -- and kill the Hive Queen in her lair. Only then, can you finally stop the flow of demons into the land.
