Very fun game. You start off as a little pup in the streets of a city in tokyo, roaming aroundjust trying to survive. Eventually you can unlock other animals. It's especially fun being a velociraptor.
inFamous: Blood Carnival
Very short campaign, but the game is just so fun to play. Unlike the other inFamous games, this one is actually fun because you don't have to worry about choosing a side, just about powering up. Plus, you get to be an eltricity-controlling vampire!
Game based on an anime based on a manga about a dead gangster who comes back to life to protect those he loves with awesome gunslinging action. It's a PS2 title but you can get it on PSN.
Way of the Samurai 4
All the Way of the Samurai games are amazing, this latest being the best. You're a samurai in Japan on the turn of an era where europeans and guns are introduced to Japan. You walk around, encountering people. Some attack you, some don't. You can choose to do 'missions' which progress the story, or just go around fighting everyone and everything. Plus you can create your own weapons from different parts, and trust me there's a lot. It's a game worth playing, one of my favorites.
all these are from PSN, definitely worth the money.
