Earlier this week Ubisoft made it clear that — in the foreseeable future — Watch Dogs will be the company's only "mature" game on Wii U. It's a decision that makes business sense due to Ubisoft's struggles with the system, as the company aims to release and target games that typically sell well on Nintendo hardware.
While it wasn't exactly a positive statement from the company's Yves Guillemot, Ubisoft is keen to emphasize that it's still supporting the Wii U. The publisher's European boss, Alain Corre, has been more optimistic in his tone around the system; he's emphasized that he thinks Just Dance 2015 will do well — Nintendo could do with some of the game's loyal fans switching up from Wii — while sharing a belief that one particular first-party game could galvanise the console.
To be honest, we always want more consoles. Just Dance 2015 is resonating very well. We think it will please a lot of [existing] Wii U owners and push more families to buy extra Wii Us. But we also believe that Super Smash Bros. will be a trigger to increase the momentum of the Wii U at Christmas. As a gamer, I was playing [Super Smash Bros.] over ten years ago, and it has some of the best moments that Nintendo has shared. I think that franchise could be magical [for the Wii U].
Nintendo has some of the best franchises in the world and it knows how to make great games. It proved that with Mario Kart, and it will prove that again with Super Smash.
Even if Ubisoft is limiting support to more accessible, family-friendly games, those sorts of titles could still be important for Nintendo in the Holiday season. We trust that if Smash Bros. does the job in shifting systems, meanwhile, that Ubisoft will release its game that's already finished.
