There's two available editions: 1) the Collector's Edition for $24.99, which features all five episodes, an art gallery and videos that include behind-the-scenes segments and trailers, and 2) the Special Deluxe Edition for $44.99, which comes with everything in the CE plus physical post cards, a copy of Emmett's notebook and a photo album of Hill Valley.
The Special Deluxe Edition is apparently limited with only 2,500 copies to be produced. It also says "Limited 1 discounted Deluxe Pack per game purchase". Not sure what that means, exactly. Maybe if you buy more than one, the second will cost more than $44.99?
I think these sets are incredibly awesome. I don't game on my PC at all, but I think these would be great to own as I'm a big Back to the Future fan. I've already played these on my PS3, so it may be worth it just to own them as collector's items. I love how they both feature spoofs on the film series' original cover art/posters, too.
