APB is a game of contrasts. The core of the gameplay is solid, but the execution is terribly flawed. There is a lack of the dynamic gameplay promised and touted by the developers, and the lack of breadth hurts the game considerably. Despite being one of the strongest action MMOs Big Download has ever played, with a customization system that rocks our world, they can't in good faith recommend APB to early adopters.
There's just not enough there. Wait until the game drops in price or recieves content updates. It's simple not worth the $50 + subscription fee at the moment.
