PS3, and the Wii, I really dislike the 360, just because micro$oft use only one strategy: buy EVERYTHING!?!
And I find this a very low method of creating a console.
Well not really console, but as with the most consoles, you create a bond with developers, and nurture these ties. Especially when good games come out of it.
Microsoft goes to a already established developer(bungie anyone?) and just writes a blanc check and says: make games for us, and write down anynumber you want. We have more money than god...
That, and my videogame craving are satisfied with my PS3 and Wii xD
