This is probably one of the best MMORPG's I have played on the iPad, they only other been pocket legends. Order & Chaos is pretty good. The controls are not to bad, work pretty well considering their is no mouse. The game has quite few features like RIFT and WOW. I took part in a dungeon run. Itis also free to play once you have bought it
On the down side the graphics are a little basic. Also their seems to be a lack of animations. For example the charge skills has you just appear next to the thing you are attacking.
I will carry on playing because of the convenience of having it on he iPad, however I hope these kind of games carry on to evolve on iOS with I proved graphics.
