New Super Mario Bros. Wii is easy to understand. Mario Galaxy 2, a little less so. To help get fans of the former to purchase the latter, Nintendo will be bundling a DVD instruction manual with the galactic sequel.
You can see a preview of the DVD, which is for the European and Japanese markets, below. it's an interesting decision, especially given the Wii's lack of DVD playback functionality. Still, we were only bemoaning the death of the manual a few weeks ago; it's nice to see it given a 21st century facelift!
