What matters to people is that a system has sufficient amount of games for it that people want to play.  It is entirely possible that if more than one system has this, then people can own more than one system.  There is no law against it.  This is why you look at the entire library, and what is available, and see if it matters to you.  If a system has more games, or even more exclusives, but they of less interest to someone than a system with less of both, but has certain titles that are must have, that is what matters.  Same goes with system functions:

* If someone cares about the best feature points for integrated online play, AND is willing to pay for it (plus the system has the games they want), then the 360 is a better choice than the 360.  Also factor in wanting to get demos of every game.  The 360 has this, while the PS3 doesn't.  Same goes with wanting fullbody motion control, as opposed to just mapping hands.

* If someone wants a Blu-Ray player, and a game machine, then the PS3 is the choice... if the person feels the library is large enough.  On this, it doesn't mean JACK that the games are exclusive or not.  Suddenly getting a Blu-Ray player that plays football isn't an option, because Madden (or FIFA) is on the 360?  And the same goes with if you want a more accurate version of the Wii controls and play in HD (and more hardcore games), as the PS3 is the best choice.

* If someone wants Mario, and inexpensive motion control, and also old NES or SNES games that can play on their TV, then the Wii is the best choice. 

* If you want a cell phone that plays games, and has a large library, then the iPhone is the option.

* Want portable 3D gaming that doesn't need glasses?  Well, you then have the 3DS.

What matters to people is the total package of what you get with the system now, and until the end of the life cycle.  Anything else is just fanboy fodder.  And it gets VERY tiring.  And yes, you will likely want to "Yeah but..." what I wrote above.  If you are a fanboy, then you will look at the minutia, rather than the point I am making. 

The reality is that people don't play exclusives, or entire libraries. People play GAMES.  They use content.  They don't use scoreboard items.  The concept of "library size" or "exclusives" is irrelevant to the discussion, unless you are a fanboy trying to keep score.  Well, it is also possibly good you look at this to understand the videogame industry, to be wiser.   BUT, this understanding should make you more balanced, not a fanboy.

And I will close with this line to the Neo-Geo theme song: OK so we all know that Neo Geo MVS arcade cabinet is the best thing to ever exist on the planet. That's obvious. If you were born then you know that. If you don't know that then you're technically not alive. So you might wanna get that checked out.

But the PC is so much better than the X360. It offers pretty much the same games and has a better online with mods and such o_o. ITS A PC DAMNIT.

Whilst the PS3 has more games that are not available on the PC.

...Exclusives :0

Mmmm'k, fine.  And I can get a PC that does what the 360 does for $300 or less, right?

Again, it depends on what you want to play, and features you want.  So, let's see... what exactly does the PS3 do better than the PC, besides your "exclusives" argument.  You going to argue Killzone 2 blows away what is on the PC? 

would the wii fans be more interested if they knew that he lists the wii exclusives and says how wii owns xbox 360? cause he does.

there's no other system with such a limited library as the xbox360, that's the point

all the xbox fans usually say is that there's not enough games they want on a ps3 to interest them in getting one, i find that hard to believe. it's much more natural for me to say that it's the last system i'd ever buy cause there's like one game on it that i might like that i cant play on pc and it's not that great.

just cause we are fans doesnt mean we cant be rational.

edit: oh and i wont answer any replies to my post. it's a statement not an argument. there's no arguing there.

Naw, not going to say KZ2 blows away whats on the PC im simply going to say:
You can't experience games like MGS4, Killzone 2, Uncharted etc anyyyywheeeerreeee else but on the PS3.
300 dollars.. let me look that price up xD. Oh, naw you probably can't find one that can play those games for that price. But my statement remains =

"But the PC is so much better than the X360. It offers pretty much the same games and has a better online with mods and such o_o. ITS A PC DAMNIT."

I guess if you have a crappy PC and just want to play games, sure get the 360. Most people I know including myself have a fairly good PC, I dont even game on it but I can run most games xO. All im saying is you can get the exact same experience on most "exclusives" from the 360 on a PC. (asuming you have one that can run it). The whole term "exclusive" isn't really that big when it comes to the 360 platform as opposed to the PS3 ( quality & quantity wise o_o [basing this off the dudes youtube video])

Also!

Best feature points for integrated online play? Im sorry but even though I dont game on the PC, I still think the PC has the edge on online play. (IF YOUR WILLING TO PAY FOR IT >:D) [See what I did thaaar?]
Im pretty sure there are not demos for every single game on the 360 xD, more then the PS3 sure but "wanting to get demos of every game" is misleading.

No comment on Kinect - Move. Could care less about both but we all see the profits of Nintendo.
