@Laep said in Is NGS all open world or are there instances/raids too?:
It can be a bit of a pain in the ass going between areas with friends / party because more often than not itll throw you in separate instances as you cross the zone borders.
You can enter the same room together using the ryuker device's "Room Transfer". It force teleports your whole party into the same instance as long as there's space.
Adding a password with "Also restrict other parties" into your party setting like in PSO2 also allows you to enter a zone with no one else, and the only way they can enter your instance would be to enter from a ryuker device's room transfer function if I'm not wrong. I didn't test the joining part of what I typed though so that one would be based on my own unconfirmed assumption, but I'm pretty sure of the part about entering a zone with no one else as I've been on Mount Magnus instances with no one for hours when I had that, and it only started filling when I changed it back to allow other parties.
Afaik the party separation only happens if it throws you into an instance that can't fit your whole party, so putting the "restrict other parties" into your party setting when zoneswapping will probably keep your whole party together [by entering a new empty instance]. Of course, this part is again, just my assumption and would require more testing or confirmation from others.
