Good quality fun.
Although I am not a big fan of MK I am a HUGE fan of DC. I find nothing more fun than watching Cat Woman clawing peoples eyes out or Joker going wild. I there for find that the violence is one of the great things about this game. It is not the kind of violence that is to brutal or disturbing for younger viewers but it does make you think "That has gotta hurt" when you see your fighter after the battle all cut and bruised.
Personally I believe this next point is a bad thing although you may not. In most fighter games I like to go wild on the buttons (button mashing) and see what wild things will happen. On this game that will not happen. It all has to be done in a certain way which I don't really like in a fighter game but it wasn't a big problem.
One big problem I had was the difficulty of the game. The first few levels of the game were easy as they should be. But as you got nearer to the end of the game the enemies became increasingly hard. To me almost impossible. For people who play fighters very well you may not find this a problem but I am just a casual gamer so I did. The game does overcome this problem by every time you lose the enemy will gradually get weaker. Although this is a good thing I had to lose 7 TIMES on the final boss just to beat him. It does kind of make you feel like a piece of c!@p when that happens, and then you feel worse because when you beat him you realise just how weak they had to make the boss. (Try it, there is a big difference.)
This game is a good game faults and all. I would recommend it to Fighter fans MK fans and DCU fans. The thing that makes me buy it is the sheer joy of watching my favorite superheros battle it out between each other. It has a sort of endless charm to it.
