Which version of Heroes do you like the most?

Provide a well-reasoned opinion about each game. Instead of just saying "3 is great!" which isn't interesting to read.

In my opinion, Heroes 5 has a terrible interface and combat system. The graphics are decent, I won't argue about that, but there's too much unnecessary stuff. In Heroes 4, when it was first released, the graphics were beautiful, and they kept almost everything in the style of Heroes 3. It has a good campaign, although it's a bit too easy. And there's nothing to say about Heroes 3; it's simply a classic. The graphics might not be great by today's standards, but it captures the spirit of all the previous Heroes games.
