I don't like HoMM 5 because of its elaborate graphics and other reasons. I have parts 2 and 5 of the 3rd game installed. Just thinking about how long it would take to load the 5th game makes me shudder, and I click the mouse on the 3rd part.
My friends and I like to play the 3rd game in hot-seat mode. And imagine how long you have to wait for loading and reloading if you play the 5th game. Besides, everything is more abstract and simpler in the 3rd part.
In general, we like to mess around in hot-seat mode. We take a large map (in particular, Apocalypse), edit them to create equal conditions (the opponent and we have equal chances + all artifacts), divide them into teams, and let's go. Now we have set the creature growth to only level 7 (i.e., weekly growth of about 23 creatures) - and I tell you, it turns into a real mess...
With this kind of game, we don't even remember the 5th part...

What did you expect? The old world has burned down - so there are only about 20 maps left:D
