I currently don't fly any ships that weren't in the game when it released on PS4 two years ago. That said, I'm not opposed to new ships, though I'd like to see Frontier get back to their roots. Give us the Boa, the Moray Starboat, the 'original' Krait as a small ship with cockpit similar to Elite 1984, etc.
While I don't fly the newer ships, it's nice having a bit more diversity when hunting pirates, etc. Speaking of, I've yet to do combat with an NPC Mamba...
On the topic of diversity, I used to see NPCs with cosmetics - cool paint jobs and ship kits. Has Frontier removed this from the game? If so, I don't understand why. It was a great in-game advertisement and made PvE more fun IMO.
