Its because the playstation houses the best games in a lot of genres, making other fanboys jealous.

Third person shooter: MGS
RPG: Final Fantasy
Racer: Gran Turismo
Fighting: Tekken
Third person adventure (soon to be): Uncharted
FPS: Resistance (when the 2nd and eventual third come out)

The wii has mario and the 360 has RROD.

Ya know, which ever side of the fence you are on, it will seem like your prefered system and games are picked on more.

 Haze was made by free radical

lol. 

 I agree with this actually!.. especially Tekken !

For the most part, everytime a Wii or XBox 360 game is announced you hear Wii/XBox 360 fans exclaim "This game looks cool, I hope it turns out well!" ... In contrast everytime a PS3 game is announced you hear PS3 fans exclaim "This game is AAA, will sell Millions and start PS3 domination!"

Indeed, the grass is always greener on the other side of the fence.

MGS is not a third person shooter, is not even a shooter, you even understand the MGS game mechanics? It's the best stealth game, THE steath game.
RPG: Final Fantasy, I agree is hands down the best.
Fighting: Tekken (Street fighter is the most selling fighting game ever, Brawl is today the most popular fighting game by faaaaaaaaaaar (so far), Tekken is not even close to be as big as the others two)
Third Person Aventure: Uncharted ( Do you even know zelda? pick any one )
FPS: Resistance (make me laugh)

The fanboys are so fun.

You guys are funny

 Well, it was a bad game so it probably deserved the questioning.

Anygame that hypes what it looks like over what it plays like deserves to be questioned. 

I don't know about it being too short (I have never heard that and I didn't finish it) but was this game every actually questioned or are you just making things up? 

This game just isn't that good.  It only sold so much because it was a launch game (and don't get me wrong, not a bad launch game at all). 

I didn't think there were a lot of doubts about this one leading up to release but it was in fact pretty meh. 

Killzone 2 - See Heavenly Sword comment.

Infamous - From what I've heard this is just supposed to be bad.

Isn't it a demo and not the real game? 

I question the game but not for that reason.  I don't think the game is going to get the insane community it deserves and it will fall into a small close knit community. 

When more than one source comes forward talking about insane long cut scenes it's alright to get worried. 

I don't know about Too Human, but everything about Haze screamed overly generic.  Also the delays with Haze were a month before release when print ads were already being published with the release date so the delays are very different. 

Some games just deserve to be questioned and don't think *only* Sony games are questioned.

Halo 3 - is it going to be just another Halo?

Super Mario Galaxy, Super Mario Kart Wii, Super Smash Bros Brawl - Haven't we already bought this game?

 Also, as for Uncharted (since someone mentioned it), the game had a really unimpressive demo which raised a lot of questions.  Luckily the game at least turned out to be good.

Yes i understand MGS, i owned all three playstation versions. I spent more time shooting than hiding, so i class it as a third person shooter.

So because Brawl sells more its better? Are you a sheep?

Of course i know zelda. I owned ocarina of time. I would class zelda more of an RPG than anything else.

Why does this make you laugh? What other exclusive FPS series can you think of? All 3 halo games are the same (ive played them all) so....what...?

Did u come here just to troll?
