I absolutely love sports games so take that into account as you read what I think of it. I've played almost every sports game available for the 360 and backbreaker is alright campared to the rest. I personally think it is a good game and wroth the money, if you can find it in the bargain bin, which is what I did. I actually find most of my games there. As far as game play goes there isn't much difference to it than Madden, the layout pretty much looks the same. However it is not as good as the Madden games, which are my favorite.
If you can find it for a discounted price then I'd say go for it. Or you could even rent it, which is what I usually do if I'm unsure about a game. All in all if I were comparing this game to Madden I'd say that it's basically a dumbed down version with no real NFL teams. If you are looking for actual NFL teams then I'd say stay away from this game. Another feature that isn't the best is the online play. When it launched it received a lot of criticism as a lot of features were missing. Overall though I think this is an alright game for what it is. Don't expect it to be another Madden, though.
