The combat system with his combos may be innovative, but somehow (at least on the PS3) is not really catchy - at least for the casual player.
Until now I have not yet grasped, for whatever reason sometimes one and sometimes the other combo triggers when you press the first button.
Besides, I have so far (Game over) still problems with it to start a new combo if I do not the previous failed.
This could be assessed even with four stars, if then there were not yet the massive enemies clusters.
A fight usually includes either a big boss or a Mini Boss with 4-5 Minions.
The Mini Boss does more damage as long as his minions are alive.
Unfortunately, the Minions depend mostly on a nub and hold an in Stunlock if you are in the middle.
So most of the fighting went so that one runs away until you have a Minnion alone - then pushes you one or two combos by and then it starts again from the beginning.
This innovation of the combat system is pushed into the background and you are annoyed at the latest by the 20th so running battle.
The only thing that moved me to persevere was not perfect but pretty good story.
