So many meaningless rants and declarations of eternal love, and so much negativity towards other projects...
Hmm...
As for the topic.
I can't play any single "Heroes" game for too long. Right now, it's "week" of the third game.
I love all of them from 2 to 4. And periodically: I feel drawn to the fifth, and I launch the first one.
Each game has its own advantages. And the fourth one is definitely not a failure. A well-made patch, which is essentially what Equilibris is, eliminates a large portion of the "shortcomings" of the fourth game. And even without Equilibris, the game is excellent.
What are the advantages and disadvantages of the third game? In my opinion, the main disadvantage is the "castle" circus: 9 factions is too much. The classic scheme: death - life, wizards - Warlocks, nature and strength first appeared in the second game and were successfully transferred with minor changes to the fourth. And since my first experience with the "Heroes" series was with the second game, then the fourth, and only then the third, it was not easy to get used to 9 factions (races - call them whatever you want), and I really didn't like this inconsistency...
Also, I used to find the interface of the third game inconvenient (again, compared to the fourth and second), but I'm playing it.
As for the advantages: dynamic, vibrant, in many ways convenient, atmospheric - all the same heroes, and this is more of a simple merit of the third game. An excellent game from an excellent series.
