Sony buried more than a few other surprises in GT5 that they didn’t foreground much in the lead-up to release (the rally courses are procedurally generated, for crying out loud!). All I can say is I’m very glad I put serious hours into this game before passing final judgment.
Regardless, sitting around picking nits is missing the point. Like a quality automaker, Polyphony Digital focuses on the tiny technical details so that we don’t have to. And trust me, Gran Turismo 5 is OCD enough for all of us.
