An improved sequel over the first, but still retains almost everything the first has to offer.
Oh yes, there is another change in fact, which is that the map exploring part is "real-time". Yes, the enemy don't get turns at all which means everything is dependent on your decision when to activate key battles. Sometimes you have to complete certain objectives in a given time-frame but the game is quite lenient on that.
Another recommendable point of Etherlords II is its story, and it's really good! The twist is amazingly well-conceived compared to other strategy games of this genre. It's like watching Sixth Sense the first time.
Other than that, apart from a new card species which is called the pale creatures or something, there is nothing new to the combat system. Even the graphic and sound design is reused from the first game. I believe that if you're a fan of the Magic card games or Etherlords itself, you may be interested in this. For newcomers, I suggest you skip the first one and start right from Etherlords II for a better turn-based strategy experience.
