if they did there would certainly be no trainer as this sentence is very important to read:
WHEN YOU LOGIN INTO THE GAME THERE IS THREE OPTIONS
1. SEARCH FOR AN ONLINE SESSION
2. CREATE AN ONLINE SESSION
3. SQUAD SESSION SEARCH
NOTE *DOING ANY OF THESE OPTIONS WILL RESULT YOU ENTERING ONLINE MODE"
i WAS NOT ABLE TO FIND A WAY TO GO OFFLINE
Quests also are posted online so others can help you and yes you can make it so your the only one but im not really sure if it is or isn't still connected online.
creating or joining a guild is considered online
also one last thing is there is a place that is connected to your world its called THE GATHERING HUB where you can join other players. but still not sure if its really a seperate area that just online.
1. Wrong.
2. Wrong.
3. Wrong.
Also wrong that it's not coming to PC.
In any case the online universe is not persistent. All user data is saved locally. Same as with No Man's Sky. The game qualifies for a trainer and will likely have one soon.
