The Xbox One uses the 'Xbox Live' network for communicating and playing with friends. PS3 uses the Sony network. The two cannot interact with each other, so no, you two cannot play together.
No the Xbox 360 Is compatible with some Original Xbox Games although Can not be played online as there was an update because Microsoft wanted more people to get the xbox 360
The answer is simply no. you cant because play station is made by Sony and Xbox is made by Microsoft, so there's no way of connecting together from a PS3 to an Xbox(or Xbox to PS3). They got very different systems. :)
No you cant.
The legit online Microsoft store. If you wanted to get them without paying for them, sorry, it doesn't work that way.
No the game is not cross-platform online, so people play the PC version together and people play the Xbox 360 version together, but a PC and Xbox 360 cannot play together on the same server.
No, the Wii and Xbox do not connect for any game that's not possible. The Wii online gameplay is much slower due to the controls. If Xbox and Wii connected together on most games, (especially Call of Duty) the Xbox players would have unfair advantages and pwn the noob Wii players.
The Xbox, and Xbox360 can be purchased online. The newest release Xbox 1 is also available online,at retail web sites and Amazon. If there is an Xbox that you are interested in , it can be found online.
Xbox Live
Firstly, because Xbox and PlayStation use different servers. Secondly, because PlayStation and Xbox do not have connected accounts, so it would be possible to have multiple people with the same name online. Thirdly, Xbox and PlayStation are directly in competition with each other, why would they work together?
There is no "The Xbox Live", Xbox live is simply a pay-to-play game service where you can play Xbox 360 games online. It depends on the game if you can play it online or not, the game's box should on the back say if it can be played online.
You do to play online on the Xbox 360 only. Other systems also have online games
No, an Xbox live silver account does not let you play online.
