Sony has quite a collection of PlayStation Network titles, many of which I'd argue can outshine a standard retail game. Journey ring a bell? My point is, Sony probably recognizes this and, according to an Entertainment Software Ratings Board listing, could be gearing up to release a PSN combo pack featuring the "best of PSN."
The ESRB listing reveals a bundle called "The Best of PlayStation Network Volume 1," a compilation that includes Fat Princess, Tokyo Jungle, Sound Shapes, and When Vikings Attack. While we were more critical of Fat Princess and When Vikings Attack, both Tokyo Jungle and Sound Shapes received impressive review scores here on GameZone.
Sony has not yet confirmed the release of this bundle, but we've reached out to them.
