Yeah this game is pretty damn amazing; I'm really happy they got rid of the massive amount of randomness that's in the HoMM series. Having a leveling tree is so much better than just a random choice each time you level and the magic runes system is really cool. I also like how the monsters "chase" you on the adventure map, so you can sneakily get around powerful monsters! I *WOULD* like to see more classes such as Thief or Bard.
I also really like the quests. They're pretty interesting, some are funny and I'm not really bored of them. I also like how some have "non-aggressive" solutions. All of these tournaments and trials you can do is neat as well as being able to upgrade your items by "fighting" the item
I love it! If all that stuff was added to HoMM6, it'd be such an amazing game
