Taking key elements from Fable and Prince of Persia and adding some post apocalyptic FPS action should make for an exciting night in with the PS3. And yes, inFamous is an enjoyable sandbox game with enough plot and superpowers to keep you entertained for as long as you can hack the bleak city's challenges and, unfortunately, drawbacks.
While the ability to roam free is a very appealing aspect to the game, everything looks the same after a while and you begin to find that lack of variety is a problem throughout. There are not enough enemies to fight and the grey tones and dilapidated buildings begin to weigh on your superhero high spirits after a while.
That is, of course, if you choose to be a hero. This concept is how the makers of inFamous have tried to connect and appeal to their audience, and it certainly does make the experience more interesting. There are key moments added to the gameplay which determine the balance of your hero Karma and the direction the story goes in. Although the core narrative is mainly unchanged by your decisions, they affect aspects such as your popularity with the public and the nature of your powers. If you are a hero your electric blasts will be blue and more accurate-causing less civilian damage. Bad guys generate more destructive red sparks as your powers grow and develop.
As you travel around the city (I recommend surfing the railways in style), you are given missions to complete and uncover more mysteries surrounding the 'big explosion' that caused all of playable protagonist Cole's problems. Some challenges seem impossible and become time-consuming and tedious which can put players off at the beginning of the game. It is not always as simple as you'd like to find out what you are supposed to be doing but firing electric bolts around in the meantime is amusing enough.
I would recommend this to Eurogamers who enjoyed the fluid, urban style of platforming in games like Prince of Persia and Mirrors Edge (except here the controls are much simpler and it seems that falling from multiple stories has no averse effect), and will enjoy a story with a few twists and a fair amount of freedom to electrify whoever you want.
