EA isn't the only company to hit on the idea of a one-time-use code for online play of sports games. THQ is penalizing used sales of UFC Undisputed 2010 in exactly the same way -- and, since Undisputed will be in stores next week, THQ is even beating EA to it.

Pastapadre discovered that copies of Undisputed will include a code on the back page of the instruction manual, required for online play. THQ confirmed the existence of the codes in a statement to Destructoid, adding that "Codes for accessing the content will be available for second-time buyers for an additional $5." So, right now, THQ is winning the price war in terms of online play privileges. Well, not counting all those companies that let even second-hand buyers play games online without additional chrages (for now).
