“While EA Sports has an exclusive license to use names, plays and other elements of the league, the N.F.L. has editorial oversight. Mr. Langley and others vet thousands of pages of recorded scripts and delete inappropriate dialogue, like the harshest trash talk. Chop blocks, helmet-to-helmet hits and other illegal plays are not permitted in the video game — even with accompanying penalties — despite the other efforts at realism. This stems not only from the league’s fastidiousness about its image but also from Mr. Madden’s insistence that the game be exciting and educational.”
