This game is awesome.
But then I never played the first two.
The first two are old school RTS, while this is turne based 4X.
The game got a good campgain, coop, custom senerioues, random maps. Lots of races, like orcs, goblins, elves, humans, dwarfs ect.
Not only do you have diffrent races, but diffrent classes, that give diffrent spells and units. you build cites, take over cities, create new cities.
The game was kinda Marketed/talked about as a fantacy Civ 5.
But really it's more like Heroes of miight and magic 2/3 with just a sprinkle of Civ 5.
I have not enjoyed this type of game as much since Heroes 3!
