All this makes me realise I've been playing this game wrong....
See, this is the thing...
Any veteran player of ED would tell you that you've got the right idea.
There is no "destination" in ED. The game is 100% about the "journey".
You will, literally, have exactly the same experience while flying a Cobra and earning Cr500k/hr as you get while flying a Cutter and doing, erm, whatever people do in those things.
Trouble is, it's almost impossible to convince a newbie of that.
Instead, they start playing, they see expensive stuff, they want it and - with the addition of nu-mining - they have the ability to get it within hours.
And then they get the stuff, they realise nothing has changed and they wonder what they're supposed to do next.
It's kind of like playing Skyrim and immediately allowing a newbie to craft legendary weapons and armor, go straight up to the summit of The Throat Of The World and slay Alduin.
If that
was possible, you couldn't blame newbies for wanting to do it but it
would ruin the game.
When it comes to stuff like that, it's up to the dev's to create soft barriers that prevent players from doing stuff they're not indended to be able to do or they risk undermining all the intermediate content they've created, and that's a responsibility FDev seem to have abdicated.
The "best" way to play ED (IMO) is to just do the stuff you enjoy doing and don't try and strive for anything.
By all means, dip into nu-mining to bankroll a specific project (to buy an FdL if you enjoy combat or buy an Annie if you like trading etc) but don't get sucked into feeling you you always need to have more of everything.
Every step of the "journey" in ED is as enjoyable as any other (no more and no less) and there's no "destination" so if you're not enjoying what you're doing in ED then you're wasting your time doing it.
