Videogamer.com reviews PES 2008:
"Such was the disappointment in the next-gen versions of PES 2008 that the PSP version has taken on an even greater importance than usual. The result is a thoroughly decent effort, one blighted by technical problems like its next-gen big brothers, but in many ways it eclipses them in terms of raw gameplay.
This is, as you'd expect, a stripped down version of PES 2008, sans the commentary (you'll get a single line whenever a goal is scored, which feels odd) and much of the crowd and stadium effects. The graphics hold up extremely well - probably because PES 2008's graphics, at least on the PS3 and the Xbox 360, came across as last-gen with a lick of HD paint. PES 2008 PSP doesn't have the HD lick of paint, of course, but that doesn't stop it from being a decent effort."
