To download it, yes you do, but once you get it you do not need a live account.
No. But you need it to down load the game.
No, the Xbox version of Minecraft is for Xbox360
I believe no. i am a Minecraft pro on the PC version but i don't you need it. maybe for multiplayer. and minecraft is better on the pc.
No.
Well it depends. On minecraft u can live a virtual life and play with Other ppl with a server. On Xbox Live u can Play with other ppl and talk to them at the same time. My opinion is Xbox live.
no.
you dont have to be online, but you wont be able to play with others (if you have gold)
Yes, you need to be on live to use the Game Marketplace in order to buy Minecraft.
An Xbox 360, and enough points to buy it on the store.
The only way you can be in multiplayer you have to get xbox live account then you have to get xbox gold for it (-you have to buy it) after you get xbox live you can add your friends but they have to have xbox live and xbox gold to play with you.
To originally purchase Minecraft yes, but from then on it can be run without Live!
minecraft is played on PC, Mac and Linux but can soon be played on xbox live arcade
You'll need a friend with you in real life, so you can share a screen. Your friend will have to add their controller, and then you can play. As for XBOX Live, split screen isn't needed as your playing on different consoles. Just invite them to an XBOX party and you can invite them to your minecraft game, no split screen needed.
