Nintendo doesn't make the best game.
But I believe, although I haven't played the last iteration of games on Wii U, they are the best art directors for Platform, Fantasy Adventure, or Multiplayer Fun games (SSB, MK or MP).
It's not just in the style which has been around for years now, it's about the craft, the choice of texture, of dynamics in gameplay and animation, even sounds...
Nobody matches them for these specific genres.
However, when it comes down to action, RPG or adventure games for example, well Square-Enix still are king of art direction for RPG, Naughty Dog and Konami are the best for Action game, and Ubisoft are starting to be serious about Adventure game or at least for 2D Platform/Adventure game they're the best.
