The campaign is soo completely different to the real game it should not be called a tutorial, you dont have to do any research; it is all given to you the enemy creatures toward the end can easily wipe out your "reinforcements" with their 10 damage to all nonsense that has no damage level mitigation and no random dice.

Your main Hero in the campaign has significantly more life than you wiill see in most hero's in the real game except if you chose to only give hp oon level up , and then you endup with a nice useless target , but they can live long enough for the rest of your troops to kill the enemy, instead of the quick death.

The enemy towns some don't even start withh an influence area, and thus break the gameplay when it come to getting gilden reinforcements as it seem you need too get into their territory to trigger the event, can't even talk to them to trip the event.

There are no random spawn explorable points even the one "well" in the campaign has nothing attached to it

It does not even teach you how to create units really , here have some troops off you go. Your cities grow so slowly that even city growth would barely happen if you thought to build a house, and that would only count if you discovered hot to build the farm. Tutorial suggests more of a guide on how to play a game not just a plot layout you run through.
