GameNTrain author Simon Marshall writes: Undoubtedly, the PS3 and Xbox 360 era of games will be remembered as one of the best generations this industry has ever had to offer. When you think of timeless classics such as Bioshock, Uncharted, Left 4 Dead, GTA IV, Assassin’s Creed II and even something as recent as The Last of Us, you get a feeling of just how much gaming has come from two sticks hitting a ball to one another. For me, one of the most defining games of this generation was something which seemed to be over in a flash. A fad that has seemingly been forgotten due to one series bleeding the idea dry. Although Harmonix had created the first two Guitar Hero games, everything fell into place once Rock Band was released but, for me, Rock Band 2 changed my perception of gaming.
