Why should nintendo ask for a sign of good will? they should be happy a large amount of devs finally is interrested in their platform after n64 and gc. What happens in Japan is also of some importance for NA/EU. After all a fair amount of games ''we'' play are from japan.
The hypothetical scenario I'm thinking about would be a Japanese dev who traditionally hasn't done well on Nintendo systems or in NA and are reluctant to support the Wii in NA even thought they are doing well in Japan. As good as Nintendo is doing by some measures they can still use all the 3rd party support they can muster. So they approach this Japanese dev and ask them to make a few games for NA. Would this devs Japanese success influence their decision to support the Wii in NA even though they haven't traditionally done well in NA.
I just wonder if that's how the industry works sometimes.
