There are two big soccer games out: Fifa 13 and Pro Evolution Soccer 2013. Kotaku already provided advice on the differences so perhaps you could make your choice. But if that wasn't enough, why not judge the games on which one can render things like Wayne Rooney's head better?
The Official PlayStation Magazine UK had the two games face off by seeing which ones did better jobs at reproducing the likes of Lionel Messi, Gareth Bale, Franck Ribery, Rio Ferdinand, Gervinho, Marouane Fellaini, and Marouane Fellaini's hair.
