How will single player work? Will I need to connect to a server to play?
The galaxy for Elite: Dangerous is a shared universe maintained by a central server. All of the meta data for the galaxy is shared between players. This includes the galaxy itself as well as transient information like economies. The aim here is that a player's actions will influence the development of the galaxy, without necessarily having to play multiplayer.
The other important aspect for us is that we can seed the galaxy with events, often these events will be triggered by player actions. With a living breathing galaxy players can discover new and interesting things long after they have started playing.
Update! The above is the intended single player experience. However it will be possible to have a single player game without connecting to the galaxy server. You won't get the features of the evolving galaxy (although we will investigate minimising those differences) and you probably won't be able to sync between server and non-server (again we'll investigate).
How does multiplayer work?You simply play the game, and depending on your configuration (your choice) some of the other ships you meet as you travel around are real players as opposed to computer-controlled ships. It may be a friend you have agreed to rendezvous with here, or it may be another real player you have encountered by chance. All players will be part of a “Pilot’s Federation” – that is how they are distinguished from non-players – so you will be able to tell who is a player and who is a non-player easily.
You will be able to save your position in certain key places (probably just in space stations, but possibly while in hyperspace too, if we feel it is needed). A save-and-quit option will be freely available at those points, as will the subsequent reload, but there will be a game cost for a reload following player death. Your ship will still be intact in the condition it was when the save occurred, but there will be a game currency charge (referred to as an insurance policy) for this. This is to prevent the obvious exploit of friends cooperating and killing each other to get each other’s cargo. If you can’t pay, then it will accumulate as an in-game debt, and the police may chase you!
There are no multiplayer lobbies, and the game will be played across many servers, augmented by peer-to-peer traffic for fast responses. Session creation and destruction happens during the long-range hyperspace countdown and hyperspace effect (which is a few seconds only), so is transparent to the player.
We have the concept of “groups”. They can be private groups just of your friends or open groups (that form part of the game) based on the play styles people prefer, and the rules in each can be different. Players will begin in the group “All” but can change groups at will, though it will be possible to be banned from groups due to antisocial behaviour, and you will only meet others in that group.
