It gets booring too fast.
It's too easy, after having ended the Story once, you can go in the Unlimited Mode nearly without moving the mouse due to the upgrades.
For those with problems with the drums, bass and so on (everything but the main song) I'd recommend to also look at how the symbols are, they give you an idea about how they sound, letting you to know whether they are at the beginning of the sentence or in the middle of it.
Needs badges, surely.
But... why it have not a clear objective?
And why is there no reason to rush?
I mean, you can take the first turns to provide a big amount of income per turn and then start conquering.
Everything perfect except that after completing the Campaign and pretending to play Multiplayer... I realize I'll have to play the Campaign again on Ninjakiwi...
Ok, after playing the whole game (both paths) I realized that's not the only "booring part"...
Really disappointed that they made such a game after the great first and second chapter...
