Do you still play Heroes III?
If you haven't played for last 5 years, there is a great news: new, unofficial, stable expansion pack called Horn of the Abyss was added about year ago.
It's not buggy as WoG is. It's refined and when you play it seems to be next official pack, moreover, it's still updated (last update was two weeks ago).
What's new in HOtA?
- improved graphics

- new campaigns
- improvements for existing objects
- new artifacts
- bugfixes for three previous versions
