Recently, fans of the Super Smash Bros. series (including myself) have expressed concern about how the new Game for Wii U and 3DS will play; we’ve been worried that since Namco Bandi is developing the game for Nintendo, it might not use the same tried and true gameplay mechanics of the other 3 stellar titles in the series. Fear not gamers around the world! In an interview with Dusty Cartridge Tekken series Director Katsuhiro Harada stated:
“Although we’ll help provide support on technology and other things involved creating the game, I’m currently very focused on the Tekken series. Some people might say online that I’m going to be involved in the development process or not but that shouldn’t really be an issue because the game design is going to be handled [by] Masahiro Sakurai. So I don’t understand why there would be any worries there.” -Katsuhiro Harada
So now you can all rest easy. You’re Welcome. -Dallas B.
