I am inclined to agree with everyone about SE not bothering to fund the dub in other countries due to fearing a loss of money. But, wouldn't boycotting it, like you seem to be dead set on doing now, only do the opposite of what you want? I mean I have never boycotted anything before, but I don't know, you seem to think not buying the game will change their mind about translating it when people not buying the game are the reason they aren't translating it in the first place... So it would be counter-productive? Maybe? (If I am way off base here, I apologize)
I would be more inclined to agree with what Spock said and to try and show Square that you all do car, and that you do want this in your language. And if that doesn't work, then an online guide made by fans is a decent alternative. I am not fluent in Japanese, just as you are not fluent in English, yet I know enough to get me through the basics and I have enjoyed many Japanese games. I mean that is just my two cents...
