I picked up a DS from a friend for a couple different reasons. One of the main things was using the DS with our Wii. Only to find out it that it only works with 2 games. Come on!!
This has got to be one of the coolest ideas around, I only wish it was supported by more games. All of the posts I see about it, people are complaining that Nintendo needs to utilize this option. However, the DEVELOPERS are the ones who need to tap into the power.
They are already dedicating specilized programmers to writing Wii versions of games to incorporate the controllers and lower graphics, it's time get the DS involved.
There are all kinds of possibilities, the biggest one being that you could pick plays for football without the other player seeing. How about interaction using the touch screen. I would love to see a Mystery Case Files for the Wii, using the DS as your "tool box" or your "briefcase" or better yet as your maginfying glass.
How about a spy game using the DS as a com link??
Maybe someday, but for now all we can do is write blog posts like this.
