Hi Oddworld fans.
We've looked into the 'partial' controller support tag and given that you can start the game from Big Picture Mode, operate all the menus, start the game and quit all using an Xbox 360 controller, we think 'full' controller support is more appropriate, and have therefore changed it on the profile page.
We'll continue to revise and expand on the Steam page, including the GPU requirements, in due course.
Thanks!
