Character mistake: In the opening interview, one of the options during the question about playing styles is "I am a big fan of Pete Sampras or (sic) Roger Federer." However, due to licensing issues the ace Swiss player appears in the hall of fame as "Roger Feberer." It can't be both.
Character mistake: Despite the obviously heavy presence of female tennis players, in the interview section every question directed at a player managing a woman does not adapt the pronoun, so it's always "He won", "his form", etc.
