If i download the demo will I have to download the game again when/if I buy it?

and does it use up much downloads while playing?

I only get 4gb per month

thanks!

I remember it did yeah, also save files don transfer over from demo to real game.

I think the game itself is 4GB ><

yeah, with patches now, game is pretty big, i suggest downloading it somewhere else, if its not possible and you really want the game, you can usually buy an upgrade in download limit for a single month, latho I'm not sure how much that costs and if its worth it.
