People who always demand new ships, new weapons, and new gameplay will never be satisfied, because today's new gameplay and today's new ship is tomorrow's old gameplay and ships. If 27 ships is not enough, how will 30 ships satisfy you? If the dozens of different gameloops per career isn't enough, how will one more make you happy? You can trade, pirate, fight wars, mine valuable metals, bus passengers, rescue people from burning stations, hunt other pirates, work for factions, work for player groups, and dozens of other things in this game already. What else do you want? Maybe if Elite added a dishwashing gameloop, would that make you happy?
That's not to say that the gameloops already in Elite don't have room for improvement. I'd love to see all the half-baked gameplay features be fully finished and polished like fine Japanese cutlery. In fact, I'd much rather see this than yet another ship or weapon added to the game.
If you want new gameplay, buy a new game. I have plenty I can recommend you if you'd like.
