Simple Question about paying..

I will get Xbox 360 Elite sooner or later but I want to know :

Do I have to pay to play on-line with my friends ?
What things I must pay for ? Please answer and tell me everything I must know.

:)

Yes, you do need to pay in order to play online. A year's subscription to Live is about fifty bucks. Less than five bucks a months. You'll also need a headset which will run you like fifteen bucks. Thats all I know of you'd need to get thats not already included in the elite bundle.

There is still few questions I want to ask here instead of making new thread.

-Can I pay for that with Xbox360 point cards ?
-Is Xbox1 games playable on Xbox360 Elite ?

edited: yes, the Elite bundled with a headset :) and 1 month free on-line subscribtion I think.
