In the current launch build, I don't think there's anymore than the two campaigns, but they said that they're going to release expansion packs that (one would think) entail other campaigns.
I have to ask what do you think of it Ackbar?
I like the game as far as the gameplay is concerned, I have some gripes about balance between the classes, mainly how a Warlord's top tier units **** on everything.
I like the whole idea of it, that classes aren't necessarily limited by a race, for instance you can have Draconian musketeers or engineers. What's more odd are the goblins, having units like a goblin crusader or a goblin exalted, ridiculous.
Or even a goblin manticore rider, not what you'd usually something you'd expect from goblins.
Even better, the goblin succubi, most ridiculous thing ever.
Gotta say I hate the rogue most, since it seems like a rather weird class to play with. Rogues have assassins and a wide network of spies, but not something that you'd usually consider a good army. They're all like the auxiliary units of an army.
I mean in Total War games, if you had specialist units like assassins in your army, you'd usually have 2 or 3 of them accompanied by a dozen stronger "bruiser" units.
I like the game, it isn't something superb, but it sure has it's good sides. I really had a big issue with the fact that the defending unit starts moving first, but I got used to it.
I also have a problem with the durability of units, most of the units are very fragile and can get killed easily, making it hard to actually get an elite unit in your army.
What's more is by the time you level them up, you'll probably get a better standard unit than they can ever be and their promotions, although an improvement over the original unit, don't do much for the lategame Tier IV units.
Also Dragons OP. Noticed that most magical creatures, although expensive can be worthwhile, which I like.
