UFC online requires code

It seems THQ are following EA's example as they are including a code that enables online play with {UFC 2010: Undisputed}. EA's much publicised "Project $10" has seen games like {Dragon Age: Origins}, {Mass Effect 2}, and {Battlefield: Bad Company 2} hit retail with codes that lets the player download additional content for free. However, if you were to buy a used game you would have to pay a fee to gain access. The same is true for THQ's {UFC 2010: Undisputed} where people who buy a copy used (presumably without said code) will have to pay an additional $5 in order to play online. As Brock Lesnar would put it: "Here comes the pain!".
