Festival of Blood is a pretty fun game. Sure the campaign is short, but if you have never played an InFamous title before then this will give you an idea (albeit a twisted one) of what to expect from the series. There is also enough extra content that if you do wish to drag out the campaign you can. Even better, once you complete the campaign the game turns back time, allowing you to head back in and get all the trophies. What more do you want?
