Actually, it didn't. Look at the western sales of the series and you tell me if it's worth the trouble of localizing when sales would be poor to start but must also now consider the social climate of the regions.
Their decision to not localize the game makes sense. They'd likely lose money and have to deal with the negative press. All that was pretty obvious.
But given the sales of the series, apparently most people agree with my assertion that free Google is better than $60 volley ball booby physics.
The game is already releasing in English so what localisation? And digital release won't cost them a thing so the only money they're losing here is from sales.
Am I to assume you believe that localization only involves language translation?
