If you still don't understand, heres another example.
I recently bought Homefront used (Yeah I'm cheap) and when I went to go play the multiplayer it said I needed to enter a code, so I checked the code in the box of the game, and it didn't work, so the game asked me to purchase a 'Battle Code' for 800 Microsoft Points, equal to $9.99, needless to say, I didn't even touch the multiplayer, I'm much too cheap for that. :confused:
So this post, is basically me asking the community, would you like BRINK to include one of these 'Battle Code' systems or not?
