The Wii U really hasn’t seen any love from developers in its short life. Ubisoft has taken what was supposed to be a Wii U launch title (Rayman Legends) and then delayed the game so that they could release it for every other console around. EA has essentially abandoned the console, due to the consoles low sales in the months its been alive.
And if you happen to have a Wii U and are looking forward to playing Batman: Arkham Origins on some system then you might as well pass on the Wii U version. That’s because the games publisher Warner Bros. has made the decision to not include multiplayer to the Wii U version of the game. The decision comes down to the fact that there just aren’t that many Wii U units around to justify creating a multiplayer mode for that version of the game.
It sucks that the Wii U versions of games keep getting neutered, if the system gets those games at all, but really there’s not a whole lot that can be done. There’s a real “catch-22” situation here where developers won’t develop games for the Wii U because nobody is buying the system, and nobody is buying the system because nobody is making any games for it. It’s kind of sad, but that’s just business.
