According to the latest ESRB ratings list the PSN will be seeing Wolfenstein 3D sometime in the future. While the title may be a little outdated, Wolf3D is the ultimate in nostalgic gaming. It signified a new dawn and brought the gaming world into 3D.
This is more then likely a ploy to build up some hype for the upcoming Wolfenstein game releasing at the end of this year. Even if outdated it will be a welcomed addition for all you retro gamers.
