NFL 2K

NFL 2K is a Dreamcast-exclusive video game based on the National Football League. The game was made because of EA Sports' decision to not release its well-renowned Madden NFL series on the Dreamcast due to the demise of the ill-fated Sega Saturn. Needless to say, the game spawned its own series even when the Dreamcast died, which combated the Madden series until EA bought the NFL license in 2005.
