The reason given for the delay, was so that the developer could optimize the performance of the Wii U version “dramatically.”
The good news is we found a few ways to optimize the performance of the Wii U build of World to the West dramatically!
The bad news is that it will take a while to implement across the whole game, so we’ve chosen to delay the Wii U release of the game for a few weeks until we can deliver the game in its best possible state.
Rest assured, the game is still coming out on the Wii U (we love that darn thing), and we’ll let you know as soon as we’ve set a new release date.
