This game is a gem!
After discovering the second one as a kid, I've been playing the 3 since its release in 1999.
The ability to add new factions and the balancing improvements brought by the unofficial (and free) expansion Horn of the Abyss further enhance its already endless replayability.
The map editor also allows you to create your own adventures and share them.
I just spent the last five years creating a map inspired by Jules Verne's novel "The Mysterious Island".
In less than a month, I received over 1,000 reactions and my map was downloaded more than 2,000 times — this community is amazing!
Long live Heroes III!
