Wii U version of Injustice is missing stuff. No lobby system online (which I think means online practice is gone). Doesn't tie into iOS app.

Lots of noticeable video compression, longer load times. You can put a movelist on the screen, if you want. Fighting's fine, at least.

So the core mechanics are there, but it's clear that this isn't the best version of the game, or even the best it could be. You have to wonder why third parties get upset about their games not selling on Nintendo systems when we usually get inferior versions.
