Infamous is a beautiful game, but the structure and missions get very repetitive. It's also light on content. Watch Dogs, while a little rough around the edges, is really a great game. A ton of side missions, the city really feels alive, and hacking never got old to me. If you want a graphics show piece get Infamous. If you are looking for value, definitely get Watch Dogs.
Also, Wolfenstein rocks!!! Been the best surprise for me this year.
