Injuries are not a blessing and a curse for realism. They're essential, especially for a football video game, for realism. Realism is a "blessing and a cursre". If your QB gets lit up it's a blessing for the offense that he can't get injured, but it's not a blessing for the defense.
No injuries renders the franchise mode utterly worthless. This will do BB in.
Let us see what is stacked up against Backbreaker's success:
One, they're without the NFL license. Two, the Equipment looks extremely akward. Three, there will be no injuries in the game.
Now considering the fact that consumers want realism, even though many of them may not recognize realism, or lack there of in gameplay, how does NatMo expect them take a sports game seriously when it has no injuries ?
BB is missing three major components of realism: real NFL teams and players, authenic appearing equiment, and injuries. I don't see how they're going to succeed.
