Well of course if you're speaking about xbox live. just sign out of the other persons account before you log in.
yes. you can.
A Xbox360 is a console, the second after the first Xbox. You play Xbox360 games on it and I think you can download or buy a thing so you can play your Xbox games on it to.
no you cannot
Most of them, but not all of them.
you can play on a computer or game console (ps3,ps2,xbox,xbox360)
The Arcade console supports all xbox 360 games.
In PC there is more control and accuracy is better. On console it's harder but their are more games for console. I f you get a console, get a xbox360. Play halo on it. But fore control, its PC.
No due to region locks on the console. This is also the case with the Wii, however the PS3 is not region locked
Up to 4 on the same console through split screen.
No, if that could happen there would law suits everywhere, i mean if i could play all xbox360 games on ps3 then what would be the point of buying a xbox360? so the answer is no. Actually the answer is yes if you hack your PS3 but the risk is that if you hack it, your system might be banned if you have a PSN account but if you don't have an account then your free to hack but why would you want to play Xbox games on a PS3 if PS3 games are way better than Xbox games especially because they don't get scratched that easy and they have a lot of Hi-Def which makes PS3 the superior console !
Games are tied to both console and account so there's no way to illegally copy it like that. Best way is to just get your own Minecraft and play it on your own system.
No, it is impossible to play with someone who has a different console to what you do, you also can't play xbox 360 - xbox one and ps3 - ps4.
