So how would you know which NPCs were which?
If the idea is that you can follow an NPC around to be led ro content then if only some of them do it you're essentially dealing with a mobile USS.
Disclaimer:
I think the whole idea is ridiculous - just questioning what the proposed mechanics would be.
There's a few things that could be done to help us tell the difference, but honestly I don't even think the persistent NPCs would even need to passively lead us to content, only once we interact with them.
A few ideas for telling who's who:
- Different colour on radar or contacts panel
- Different shape marker on the radar
- No scan necessary, already broadcasting their ship information and name
- Find them sitting in key, predictable spots in Supercruise (like near to planets or nav beacons) or in normal space (outside stations)
- Sitting in clearly marked signal sources broadcasting a special message (like the "seeking luxuries" NPCs that you used to see, except actually giving us some mission/story content or leading us somewhere)
- Contacting
us in Supercruise like some mission NPCs do.
The key point here is that the persistent NPC questlines wouldn't start without our input - we wouldn't need to be afraid of dropping in somewhere and missing our chance because we didn't scan or follow every NPC in the instance to see where they're going or whatnot.
I think I'm just imagining Soulsborne-style NPC questlines in the game, using ships instead of knights.
