We've gotten a few drips of information about the Journey Collector's Edition, but developer thatgamecompany has finally spilled all of the beans. It's set to release as the studio's first disc-based retail game on August 28, for $29.99.

Despite what you might think from the name, it's a compilation of all three PlayStation 3 exclusives made by thatgamecompany. That includes flOw, Flower, and Journey. A post on the developer Web site details the extras you can expect from the package.

It will include a half-hour documentary on the making of Journey, playthrough commentaries of all three games, three mini-games, concept art, original soundtracks, a Dynamic theme and wallpaper, PSN avatars, game trailers and developer diaries, and reversible cover art. The mini-games are titled Gravediggers, Duke War!!, and Nostril Shot, all created during 24 hour game jams.
