Post-release content has become a huge part of almost every major video game release. It has changed the way we view games and even evaluate them.
Back in the day, a game was released and whatever issues it had, you were forced to deal with. Now there are patches to fix almost anything. Also, developers had to put all of the content intended for the game on the disc or cartridge from the beginning.
Now downloadable content not only extends the playability of the game, but it also increases the earning potential for each title.
The WWE 2K brand is in tune with both concepts.
