Pier Solar and the Great Architects HD comes out on the Wii U today, so if your reading this go on the e-shop and grab yourself a copy.
As for Xbox One owners, you guys can now expect to play the game on November 21st, which has been approved by the boys over at Watermelon Games. That would mean that the only versions we are waiting on are the Dreamcast and Playstation Vita (unless I missed a platform?).
The game is already out on Playstation 4, Playstation 3, Steam, Ouya and (as of today) Wii U. What console are you planning to pick this up on?
