Every body is all around this ps3 or xbox360 and the winer of course is the ps3, just for the simple fact that xbox360 is just an improved ps2 only at the grafical engine, and the controls stink, its realy dry on games and same thing for the wii.
Also the wii s numchucks arnt very interesting, i mean, people can crack their Tv whith that kind of stuf or someones head, and sometimes their just to hard to work whith, just look wat they did whith resident evil 4.
About the PC, the PC is an absolute clasic whith an special taste for strategic games and shoters that work so well in it bcause of the great "mouse", still its bigest flaus are the instalement time and the price you got to pay for it plus grafical improvement.
The Ps3, has a relatively low price and the cheapest blue-ray sistem in the market and it packs some great grafs, still the sixaxis arent that good and the lack of retro compatibility is a problem.
Im also going to talk about the Ps2, i think that the Ps2 is the best console ever created, and dont give me the talk "the xbox has bether grafics" bcause thats a frkn lie, just look at games like God of War 2, Final Fantasy 12, Okami, Ico and Shadow of the colossus, those are "real" games that can show that even Ps2 games are bether than all of the xbox games and Ps3 games, did the xbox ever made a game like Silent Hill 2? I dont think so.
So you all should give a thought about this, whos bether ps3 or good old Pc?
This is my opinion:

PS3

Grafs: 5/5
Sound: 3 or 5/5
Gameplay: 3/5 the sixaxis arnt that much good and intuitive
Instalement: no need for that so its 5/5
Price: 3.5/5
Memory: 1.5 or 4/5

Pc

Grafs: 3 or 5/5
Sound: 3 or 5/5
Gameplay: it depends of the game so its 4/5
Instalement: so boring 2.5/5
Price: 3/5
Memory: 5/5

Its your choise!!!
