GAMESPOT`s faulty review system? Ratchet & Clank review!

[Skeeuk]

ive just read gamespots review for ratchet and clank quest for booty which they settled with a 7.5

now quest for booty is like an addon in a way in that its a short game.

the orig ratchet tools of destruction they also gave 7.5

does anyone see something wrong with these scores?

http://uk.gamespot.com/ps3/action/ratchetandclankquestforbooty/review.html R+C quest for booty

both got 7.5, even though tools of destruction has more levels etc and is the full game?
