I play PS3 GOTY version. Operation Anachorge, Borken Steel and The Pitt went almost flawlessly but Point Lookout has some problems. I didnt make it to mothership Zeta yet.

Nintendo

They have significant level of output and it's all quality.  Even when they go super simple, like a Wii ___ game, there is so much attention to the details of that simplicity it's amazing.  While playing games like Mario Galaxy 1/2, NSMBWii, and Kirby I regulary felt myself amazed at some of the cool ideas they snuck in (especially Kirby, which did that at least twice per world).  While I get that sense of amazement from some other games, it's usually in the first few minutes and then that's the last time they throw in the wow factor.  And I don't really buy in to graphical prowess (I'm one of those people that can't see the difference between SD and HD unless they are side-by-side), so it's really the gameplay that determines how much wow factor there is for me.  For someone who has been gaming for roughly 25 years, it really takes something special to impress me and even after all these years Nintendo is still coming up with impressive stuff game after game.  Sure, they cut corners on stuff like story, but if I wanted story I'd pick up a book or watch a TV show..  So if that's what it takes to drive innovative gameplay, I'm down.

Dont see how one can assume that being they do put out more games than anyone else. So all thats left after that is what you enjoy and if someone enjoys the games Nintendo puts out its a no brainer. The only way to make it where no one says Nintendo is to say other than Nintendo ________________. Which is why I was nice enough to include who I found to be the runner up.

Just because somone likes one company or another more does not mean they are closed minded. Pretty much everyone on a gaming board enjoys a lot of different developers. But for this youd need to pick the company you feel is #1. So if  A. company has say 30games you love this gen and B. has 15 that you enjoy.....

@pizzahut consider yourself lucky

Naughty Dog, Bioware and I'd like to say Kojima Productions 

Polyphony Digital. 

Capcom, they give every console enough support and variety.

And I'd like to say Nintendo, but even if when they try their first party games are amazingly over the top, they did sometimes give us some lame excuses for games.

I find people who say Rockstar very close-minded. That is all.

I'm not an expert. but I heard many people who highly complained about GTAIV, and the fans didn't quite love, am I wrong?

Many people on the internet are saying that, yes. But people on the internet aren't real life people. People love GTA IV in real life. That is because people in real life aren't aware that GTA IV is rated the best game of all time. They see the game for what it really is, not for what it is supposed to be.

And besides, the things that people don't like in GTA IV aren't related to laziness.

Rare or any EA studio...
