I was really stunned to hear spoken french when I first played Kirby's Epic Yarn! I think Nintendo's stance is interesting for non-english markets, allowing a lot more people to understand the plot. Unfortunately, right now, the games being fully translated in french/spanish are the ones that depend less on text... I mean, playing Kirby without understanding what they say is not complicated, but playing Zelda is another matter.
Interesting fact: unless I'm mistaken, the first console games to have been translated into french are Kirby's Dream Land on the GB, followed by Kirby's Adventures on the NES, making Kirby the first language friendly character on consoles. (I think the weird Mario is Missing on the NES was also translated) Computer games, on the other hand, were more often translated into french, probably because it was easier to do so on a computer.
Anyway, I like this new trend and I applaud Nintendo's effort in that domain.
