Nope I disagree… 
you are not necessarily connected to the game server anymore once the game session is over.
Chatting doesn’t mean much. First of all the chatting thingy could be separate/independent from the actual game server and secondly you cannot do anything else than chatting in a lobby… you are clearly not in the “game world”, you cannot see, shoot or do anything else so therefore doesn’t really count if you ask me :rolleyes:.
It is the game world. You also check your inventory, use the online shops, chat, setup rooms on lobby, etc. This is all still connected to a server. Your connected as soon as you select a server and join. The game world would be everything that revolves around the game once turned on. So yes the lobby itself and all the features on it is still the game world. The menus just are not in game like traditional MMO’s you have to be at the lobby.
How is that the game world? there are games that you can access your inventory and online shop even from a webpage, without even running the game client… so what? that’s not what I would consider the “game world” at all I mean you can’t actually use your character or do much of anything.
The lobby is not the game world! it’s a place to prepare before actually getting into the game world.
I reckon once I log into the game I am already in the game world.
