Yes, more so mentally but if you play aggressive games you are more likely to become aggressive and you will lack social skills if you play it to much. You should only play for no more than an hour a day but not everyone follows this suggestion it can cause poor eye sight and that can later give you head aches. if you have to question that fact if you play it to much you probably do. go out side go for a walk or a bike ride its much better for you.
yes but it is bad for your xbox 360
Yes
NO.
its bad
It's not bad but it's not safe because its not authorized by microsoft it can also damage your whole xbox
any age, but its xbox live...best to not have a mic, cause its pretty bad
You probably get a bad connection, try registering on the computer then login on the xbox.
I think there is something you have to get to play xbox games on the 360 if you have the hdd then yes you can
It depends! The regular Xbox has very bad quality, but the Xbox 360 has pretty good quality for music.
It looks bad because its not PS3
No, Battlefield Bad Company 2 is not a cross platform game.
Bad graphics with bad movement controls.
