maybe because they released to many to fast

No need to panic. They're both fine games and are selling well - Ratchet is at 176K globally, and European sales I'm sure will be good. That's plenty for a system which has sold only 6 million units. Haven't played Uncharted yet, but the reviews have been positive.

Games as an art-form are still pretty new, so you have to be careful of these ranking sites. They measure fan popularity more than the actual quality of the game.

 Yet Ratchet is my favorite game that was released this year and Uncharted is not far behind. Frankly I played Super Mario Galaxy and Ratchet and I put no stock in the reviews. Too many politics.

Most scores are bought by M$, many x360 games are overrated, while many PS3 games underrated. Just read some gamespot excuses for giving 8 on Uncharted and giving 7,5 to Ratchet.
Ratchet - great game for kids.
Uncharted - great game for teens and older guys, it`s not even the game, ut`s an EXPERIENCE.

Come on, giving 10 - PERFECT score to Mass effect, which has Framerate problems, textures fadings, dumb team mate AI, long downloadings, troubles with inventory and only 15h of main story with repetetive side quests, you must be biased.
Ok, game can be GREAT, game can OUTSHINE all these issues, BUT it still is NOT PERFECT. The end.
You can pretend, that the game is perfect, BUT it`s not, it has issues.
That`s why scores suck today, they are biased.
