I don't really see Sony as milking stuff yet. Sure they get sequels out, but the heavy sequeled games were only new IP's introduced this gen. They're still new worlds with lots of stuff to explore and potential story arcs to go to. It doesn't feel like those IP's have been run into the ground through too many sequels, for the most they're fresh new games which people still want to get into. Sure enough if we start seeing Uncharted 5 and God of War 5 in 4 years time I think people will be sick of them, but I think going up to a trilogy before an IP takes a 'break' is okay.

 Compared to Nintendo, where most of their franchises to me are still the exact same games they were 20 years ago. Zelda, Pokemon, Metroid etc still play the exact same as they did when I played them on my NES. So little has changed, and while great games I just can't cope with doing the same puzzles in Zelda or having to do the same turn based battles in Pokemon over and over again. 

No, you are wrong, don't go barking up this tree. PS2 is a maybe, Gran Turismo is a beast, but PS3? No. There's not a chance. The top three Nintendo games on the Wii alone (even ignoring the DS) would annihilate the entire first party library of any Sony console ever released.

Edit: Make that top five, just to be safe.

As long as Sony is making money off of a product line to sustain great products, it's probably worth their business venture/investment.  So you are still wrong.

So.  That would still not stop Sony from potentially being the "best publisher going around."

Bundled games have no gross, they are usually given away free 

An egregious and unsupportable assumption for Wii Sports, alas.

You meant Activision, right?

When did I say it wasn't worth their venture?

I said.. read it carefully now... that Sony cannot sustain its hardware predominately based on its own software whereas Nintendo not only can but has numerous times.

You remove PS1/2's massive 3rd party exclusives and other software to the levels of N64 or GC and you will have Playstation losing each gen. easy. In fact, it probably would have never had a PS2/3.

GT is arguably the only IP Sony has that sales at the level of Nintendo's top 10 IPs. Super Mario (this includes SMB, M64, NSMB, Galaxy), Pokemon, Nintendogs, Brain Age, Wii Fit, Wii Sports, Mario Kart, Zelda, etc are all far bigger IPs than anything Sony has with the one exception of GT... and even that is still below most of these.

No matter what you show, GT could never carry hardware on its own. PS has required Final Fantasy, Metal Gear, Tomb Raider (PS1), and the hordes of other top notch 3rd party titles.

what does going around mean

I thought it meant sleeping with other publishers. Which is a bit weird if you think about it.

@OT I think, that some of the games produced by SCE can be classed as world class, but then again, if you have the developers on your side that have plenty of experience under the belt, Naughty Dog, Guerilla Games and numerous others, it is no wonder that good games are delivered. What I sort of agree/disagree with is making numerous installments in the same generation, I personally think that if the game is good then why not, if the game is pants or just a previous installment with some sugar coat, then it should stop(Guitar Hero, COD).

I wouldn't go as far as to say that SCE is THE best publisher, but certainly one of.
