This game would be an amazing Free to play game. People think it's not worth the money but if it was made F2P on the Pc I think the number would shoot up. Team Fortress 2 being an example.

Or am I wrong?

It went well for TF2 because the game was a commercial success. It takes a lot of money to fund a game, and since TF2 delivered, they made it f2p and increased the lifespan and profit. Brink, however, was not that much of a commercial success. People got turned off by the problems plaguing the game, and unfortunately lost profit because of it.
