It simply wouldn't work in Elite.
Its core network couldn't support it. Mainly because of instancing and P2P.
We cant have persistent NPCs for the same reason sadly.
That said I like how Elite now plays, really smoothly on my old PC.
Also that I get really nice fps, in none over populated instances.
Fill all that space up with NPCs and Player fleets and it will quickly become too laggy for many PC players and far too much for consoles.
Recently I went to a station that had a Fleet Carrier or Cap ship installation in the same instance as the Station.
with about Hmm.... 5 or so Cmdrs there too. Because of the Cmdrs being there the amount of NPCs being created got out of control.
There were about 60 or 70 Npcs. the radar was a mess of squares and the fps went from 140, that I normally get, to 15-25 fps.
It was very very laggy and stutter ridden.
So in conclusion I prefer the smooth game play with less NPCs, over the laggy mess caused by many NPCs.
I would like fleets or persistent npcs. I just know, or feel like, it would not work atm.
