PES 2011 is a mixed bag when it comes to presentation. From an aesthetic standpoint, I'd say that the game occasionally looks more realistic than FIFA, but that's only before the framerate hitches up. Still, it won't ever hitch up long enough for you to get worried or frustrated. The players themselves look great and are well-animated. Also worthy of mention are the presentation and menu systems, which are clean, unobtrusive, and easy on the eyes.
PES 2011 doesn't boast the memorable and eclectic international soundtrack of FIFA, but what's here is enjoyable and doesn't at all sound out of place. Jon Champion and Jim Beglin do an admirable job of keeping up with the on-screen action, but once you've played your tenth match, they will start sounding like broken records. I realize at this point that I don't really have anything to say about the sound effects; they will match your expectations. No more, no less.
