The cheapest console version of Batman: Arkham Origins will be the Wii U version. It will sell for $50, while it will be $60 on PS3 and Xbox 360.
Warner Bros didn't explain why the Wii U version is being discounted, but Kotaku postulates that it's due to the omission of multiplayer from that version. "The team is focusing development efforts on platforms with the largest MP audience," the publisher said when the news originally broke.
Given the franchise's focus on single-player, and our lackluster reception to the online offering, it might behoove Wii U owners to save $10. Of course, the PC version is the best option. Not only does it include the online mode, but it also comes in at a discounted price as well.
