Ok I have a great question but there is a stipulation to the answer and you can only have ONE answer. The question is IF YOU WAS TO GIVE ALL YOUR GAMES AWAY AND YOU CAN HAVE ONE AND JUST ONE GAME ONLY, WHICH GAME WOULD IT BE?
Ok here is the catch, your answer can not be a franchise or a series, only one game. For instance if it is a game that has sequels (i.e Bioshock, Mass Effect or Dead Space) you can only pick one of the games. If it is a franchise (i.e COD, EA Sports games or 2K games) you can only pick one of the games in the franchise like Madden 08 or NBA 2K11. This is a good question as I was trying to think myself. Like if this was for the Playstation, my answer would be Heavy Rain easy. Take in account also that you can factor a game if it has SP or MP, but again this can only be ONE game in the 360 lineup. I do not have an answer at the time I am still thinking but until then, fire away.
