Regular readers of Destructoid will know my long-standing complaints concerning the farcical period between Super Smash Bros. Brawl's North American and European/Australian release dates. Despite a range of excuses, Nintendo has finally settled on a reason -- translation is just too difficult.
Nintendo's Laurent Fischer explained the above process was the reason why Brawl was taking so long, despite the fact that it takes most Japanese developers about a month to do (rather than Nintendo's six) and despite the fact that most studios can handle near-worldwide release dates these days. Games like GTA IV and MGS4 must simply be easier to localize than Smash Bros. It all makes sense now!
Which would be fair enough, except in this day and age, when nearly every developer but Nintendo can seem to handle the localization process, claiming it takes six months just makes the company look bad. If Nintendo wants to look like it can't handle international publishing as well as its competitors, though, that's cool.
