Arguably the best asset in the game is the galaxy itself, and this is extremely underused. Exploration has almost none existent gameplay which amounts to nothing more than jump and scan. It's a testament to the quality of the galaxy, that so many people still enjoy exploration regardless. Yet update after update Frontier do not flesh out exploration or offer greater depth of gameplay.
The story is true right across the board, from trading to mining. From the lack of wing missions, to poorly executed smuggling.
The problem with multi-crew has long been foreseen hasn't it (and I seem to remember you pointing this out a year or more ago). Without a complex game with deep gameplay, anything added on top cannot amount to much.
Multi-crew, by the very nature of the current game can only be a shallow experience. There are no deep mechanics to hook into for multi-crew to bring benefits to trading, exploration, mining, smuggling, pirating, deep space rescue or indeed anything else. There are no roles beyond "gunner" that Frontier can possibly offer...simply because they have not fleshed out the rest of the game.
I still have hopes that one day, Frontier will bring their attention back to each career path and make then deep and involving experiences. Again, it's a testament to the galaxy itself that these limited shallow careers hold any water at all. Imagine the same gameplay we currently have but limited to 2 or 3 star systems! The scale of the galaxy goes a long way to hide the games lack of depth. Yet with multi-crew it has become glaringly apparent.
Don't get me wrong, I love this game. I'm always grateful for what Frontier have provided here, it's been an experience unlike any other game for me. And I am also keenly aware of just how much the people at Frontier love this game. I know first hand that they have extremely deep passion for Elite. At times, it's possible to see that the problem with Elite isn't really with the developers themselves, but rather that they appear to have their hands tied, and are given extremely limited resources. And that really does come back to your last point about the game being done with limited resources. I've no idea if that is actually true - but it certainly feels that way.
Exactly how I feel Ant. Exactly. Well spoken good sir.
