Im not talking about a Pre Order Bonus..
Im taking a page out of Halo2, you can buy Halo 2, or Halo 2 Limited Edition, which costs more but has cool additional content.
Id like to see Nintendo do the same... Provide two versions a 49.99 version and a 54.99 version that would have additional content like Making Of Videos, Interviews, a Sountrack that kind of stuff.. I think it would be cool.
