"no i'm not saying these games aren't quality, i'm just merely asking what makes them so much more quality than their predecessors.

and if you read up a couple posts where i quote two different people one explaining why God of War 3 is better than its predicessors and why Galaxy 2 is better than its predecessor is my main gripe."

I don't see what your gripe is. Could you explain it?

I think most would argue that Nintendo is the leader.  Whatever the case Nintendo is pulling in cash hand over fist.

GOW3 introduced some fun fluid gameplay with an unpapralled sense of scale and direction (in art and story)...it was already a great franchise and GOW3 was no exception but it was a more complete experience than the previous two in every possible way...the game starts with a bang and doesn't stop the momentum till it ends

As for the graphics, hell yes. The only rival I can think is UC2 which is up to debate....games like Gow3 benefits from great graphics and detail...it helps create the perfect atmosphere for the game and Santa Monica did it brilliantly as well, one can say it was the icing on the cake if you will... :)

"I think most would argue that Nintendo is the leader.  Whatever the case Nintendo is pulling in cash hand over fist."

I don't know what "the leader" is supposed to mean. I understand it to mean "the leader in game quality", in which case Sony is indeed "the leader".

I can name many great games.

Sales =/= quality

There.  That is exactly what I wanted to read.

Basically, they took everything that worked wonders in the first game, and polished everything further.  Adding a few surprises along the way.

My question wasn't to put the greatness of Mario Galaxy 2 into doubt, that would be ridiculous.  It was to make it obvious that Mario Galaxy 2 (or the first one, for that matter) didn't need to reinvent a genre to be concidered as great as it is. 

It didn't reinvent the genre. And I don't think the first game did either.  But Nintendo polished it to some heigths never yet reached for a platformer.

Uncharted 2 did the exact same with the action adventure genre.  It may or not be your cup of tea.  But it's rather difficult to question the amount of polish in Uncharted 2.  Be it the controls, the visuals, the soundtrack, the story, the set-pieces, or just the overall gameplay.

The same goes for God of War 3.  It didn't reinvent the genre.  It polished it to higher heights, while still being a God of War game.  (The game does put you into incredibly epic situations every now and then.  And it's certainly the only game that made me go "WTF FREAKING AWESOME I NEED TO CATCH MY BREATH"-ish out loud, after only 20 minutes of gameplay.

I've stated earlier in this thread that for me, my opinion, my view on things, Sony has this generation reached a level of polish in their games that only Nintendo had before them.

Nintendo's games have wowed me again and again.  Even if I don't necessarily love all of their games (even in the series I love the most like Zelda and Metroid) they still offer an incredible level of polish in all of those.

This gen's Sony games are doing the same for me.

" I have not seen a game better than SMG2 this gen yet on PS3"

Demon's Souls.

I love Demon's Souls just as much as the next guy but no, I mean not only my own opinion versus yours but just about every arbitrary way to judge quality leans in SMG2's favor.

Reviewers = SMG2 > Demons Souls

Sales = SMG2 > Demons Souls

Gamer reception = SMG2 > Demons Souls 

So really the mass consensus is SMG2 > Demons Souls, and it boils down to your opinion vs his which isn't going to definitively prove him wrong or you right  

yes they are leading now
