This is by far the best game I have purchased on my iPad in a long while. For that alone it deserves 5 stars! It is crazy fun! I have had a hard time putting it down and I honestly have never said that about a game before! Im playing it with high bass headphones and even the sound I find to be amazing!
The only problem I have run into is a double click issue. When I click to leave settings it often double clicks and puts me right back into settings. I have the same issue after selecting a class. Instead of letting me select my equipment, I am immediately jumped into the game. Annoying but not game breaking by any means.
I wish there was a little more to the city part of the game. For instance when purchasing your first civic boost I was disappointed to see it doesnt unlock a unique building. That, along with visually upgrading the building upon upgrading the boost, would have been awesome! As it stands theres really no reason to ever do anything with your city... That I have thus far figured out anyhow.
To wrap things up... If you are remotely interested in this game, I say, buy it! You probably wont regret it.
