Matt Prior, the producer of FIFA 13 has said that the game looks its best on the Wii U, sharing that the graphics “are on par (with 360/PS3) and there are a couple of features that we have been able to graphically enhance.” From there, he elaborated:
It’s not going to be miles ahead, but two things we have improved just in terms of the fidelity and quality are the pitch. If you have a look at the pitch texture there’s a lot more detail in it and we’re working on that as we speak to hopefully improve it even further.
Any improvements are fine by me. It might take a full high definition television to spot them though.
