A nice little interview with Hudson on all their WiiWare titles. and what their future plans are for the service as well as DSiWare.
Q: Why have you been so motivated to include online in many of your WiiWare games. Do you plan to continue to do so with future WW titles?
A: As customers purchase WiiWare titles via internet, we believe customers can enjoy our titles much deeply by including as many online features as possible such as an online battle mode and ranking leaderboards.
