Lame. as quality is all a matter of perspective. Sales is fact.

No one's trying to say nintendo isn't the most commercially successful, people are just thinking that sony has put out the best games. 

It does not contribute to the thread other than to stir people up. If this were a thread were about a joke, then "lol" would be an understandable reply, and I have seen people banned for just "lol" before on this site iirc.

what if other people think that nintendo has the best games?

It's all a matter of opinion

When something is good, say it’s good. “If you like it say you like it”, are the lyrics to a popular song from a band named WCK. And it’s true. Why do people give flowers to the dead is beyond me; those flowers should be given to loved ones while they’re alive and can actually smell the thing. Because when you’re dead, believe me, you won’t have time to smell flowers. Is either you’re up with the savior or down with the heat. Enough of that.

Same thing with game developers. We don’t applaud them enough in my opinion, the games we enjoy took long years to develop. And never let anyone fool you into believing that games development is an easy thing, because they’re not. You want easy then go to a movie set in Hollywood, but if you want intricacy and painstaking, tedious work, welcome to the games development business. 

This generation of consoles have been one of the greatest in history. Never before have we seen such enhancements, so fast in any sector (well except cellphones with the constant rehashing of Androids and iPhones). The Wii revolutionized motion gaming, the Xbox 360 took online play to another level and the PS3 has brought us the most technically advanced experiences to date. And that’s what this article focuses on.

Think of it for a moment: The biggest, and most enhanced titles this generation have called one platform home: PS3. You’ve heard from Jack Tretton, Kaz Hirai and many other Sony executives – even Kevin Butler, that titles like Uncharted 2, God of War 3, Gran Turismo 5, and Killzone 3 amongst others are only possible on the PS3. It’s true.

But remember, those games not being possible on any other platform’s not only because they’re built on the PS3; most importantly, it’s because of the developers who make those games. That’s what make them so amazing, the devs. Recently, in an interview with Nowgamer, Brian Fleming and Chris Zimmerman, bosses of Sucker Punch, acknowledged that inFamous 2 was only possible on the PS3:

“If you look at games like Uncharted 2 that’s a game that you actually can’t do on Xbox no matter how clever you are, there’s just more processing power on the PS3. inFamous 2 is going to be the same way. You’ll look at it and see that there’s no way we could have done this game on 360.”

But why? Was it because it was built on PS3, or was it because of the technical skills of the men and women at Sucker Punch? You see, they sort help from legendary studio, owned by Sony, Naught Dog. The team showed them many secrets, and now, according to this trailer, the game will be something to behold. It’s now becoming one of Sony’s most anticipated titles in 2011 alongside Killzone 3.

The games that have received the most critical praise in the graphics, narrative, gameplay enhancing, and storytelling departments can only be had on the PlayStation 3. Look backwards or forward, and the evidence will stare you in the face:

Backwards:

God of War III

Heavy Rain

Uncharted 2

Killzone 2

inFamous

LittleBigPlant

MAG

Forward:

Uncharted 3

inFamous 2

Gran Turismo 5

Killzone 3

Resistance 3

LittleBigPlanet 2

The Last Guardian

SOCOM 4

Oh, don’t get it twisted. The Xbox 360 house some of the biggest titles anywhere. From the upcoming Gears of War 3 to Halo: Reach. And Nintendo’s Wii is home to some of the best selling titles like Super Mario Galaxy 1 and 2, and Wii Sports Resorts amongst many others.

However when it comes to groundbreaking, genre changing, industry enhancing titles, you’ll find them under one roof: Sony’s third major console, the venerable PlayStation 3.

he forgot Twisted Metal, The Agent and MGS4

I'm not sure you can distinguish a 1st Party IP from a 1st Party game. If the IP is internal, it's chances of going anywhere are nill. No, not all 1st Party titles are internally developed, but if it belongs to that company, what are you going to call it, a 2nd/3rd Party title?

Halo is Microsoft's, Demon's Souls is Sony's, Metroid is Nintendo's. In Metroid/Halo's cases (since they've been around longer) have you ever heard them considered to be anything else but 1st Party?

Besides the fact that we're off topic and that point is moot anyway, that's the furtherst I'm going with it.

Second-party developer

A second party developer is a company that is contracted by a first-party developer to make their games.
