We've already read and heard much about the Wii U GamePad, with its screen and various control methods set to be explored and tested by developers. While these features are likely to be prominent in a number of launch window titles, it seems that one in particular will be keeping it simple.
Tekken Tag Tournament 2 was a third-party title that featured in a sizzle-reel during Nintendo's E3 conference, but the fighter is likely to play it straight with the controls. After describing the GamePad's screen as potentially 'distracting', series boss Katsuhiro Harada said the following to Eurogamer.net.
Looking at the small screen and the big screen at the same time is pretty distracting for a fighting game. So we're thinking of making it useful as a way of having shortcuts. Or, by making progressing through the game more convenient. Or by playing alone on the GamePad screen.
It sounds like the developers haven't actually decided how to use the GamePad screen yet, though we may see a similar approach to that seen in Super Street Fighter IV 3D Edition, for example, with combo moves or easy button prompts available for quick access. In any case it's clear that, like the Wii Remote before it, not all games will be interested in using the GamePad's full range of capabilities.
