Well according to the game’s creator, Masahiro Sakurai, in his semi-weekly column in Weekly Famitsu (via Kotaku), he explained that the difference in the launch dates is because of the debugging process, which is usually pretty lengthy and time-consuming so in order to ensure that both versions of the game are relatively bug-free, they decided to separate the debugging periods.
According to Sakurai, “Checking is done both domestically and overseas, so for a game like Smash Bros., several hundred people are employed. So, debugging alone becomes a huge project. So much so that one of the biggest reasons for the separate release dates for the 3DS and Wii U versions was so that we could shift the debugging periods.”
We suppose that sounds like a fair reason – after all we’d rather not them rush the game out and have it chock full of bugs, right? So far the 3DS version of the game has been delayed to October but it is still expected to see a release ahead of the Wii U version, but either way we’ll keep our eyes peeled for more information regarding the Wii U’s release, but in the meantime will you be picking up the 3DS or Wii U version of the game?
