I'm cautiously interested, but have questions:

How will we interact? Are we a team in Bullet Break? Enemies? A clan/guild/whatever? 

There is no "Oh no we are trapped" aspect to this, correct? I assume not, since it wasn't mentioned, but since SAO is unfortunately super popular, I still wanna ask.

What will we be doing? I assume Bullet Break is the main thing we're concerned with, and winning it is the end-goal of the roleplay? But... how? Do we fight other Players who are NPCs? Do we fight actual NPCs? Do we do something else? It wasn't really clear to me.
