I would rather not anyone in those games speak their text.
Also, Mario Sunshine does indeed have full voice acting, except for things like villagers and such. FMV sequences have voices, but regular gameplay has text because it would be annoying to listen to their jabbering all the time. I was very dissapointed with Bowser's voice. Wasn't how I imagined him at all.
Link doesn't talk, anyway. He's a silent hero, like Crono or Serge.
