Well I am not really sure if I am supposed to be only choosing from the list above or not, but if that is the case I would have to go with Halo: Reach. I am a huge fan of the Halo series and I like all of the games so this one was pretty easy to decide. That said, though, if we are talking all time games for the 360, it has to NHL '13 because I just dominate anyone that I play if I am Tampa Bay. I realize that is not the most popular answer, but it is true. Thanks for sharing.
