I still dont see why you have to be in online multiplayer mode to see the world evolve?
I mean if i dock at a station and save my game in online mode will i be able to pick-up where i left off with all my credits / equipment / status etc intact.
Because thousands of other players are going to affect the background simulation, AND the devs will be "injecting" events in real time. Offline players will only generate their own events and effect on the background simulation.
If you're playing in "Single-player online mode" you will see all the changes as they occur in the online world.
"Single-player offline" players will only get developer related changes through game patches and updates.
It's not X-Series... those are ONLY single-player. It's an entirely different system.
