Funny thing is, I believe stories like Ellen_K's are quite similar across the board of players who are in the game for the long run:
0.) Why buy the game? Because Space!
1.) Had a Sidewinder. Did stuff. I seriously do not remember what exactly. A little bit of everything, with a lot of goofing around and creeping towards the galactic core. Until I could afford an...
2.) Adder. Which was on the second day of playing. Traded some, started wandering further corewards through the populated regions, did a lot of NAV and RES bounty hunting and went for a high-tech system as close a possible to the core. Back then, travelling 150 LY seemed like a challenge. Didn't like the high-tech system I went to, but, lucky enough, I found another one next door that's great and has been my "home" ever since. Bought a Cobra. (Four or five days in.)
3.) First exploration tour: Only goal: Find something to put your name on. Did so. Two hours there and back. One of the most defining and beautiful moments of the game for me, by the way.
4.) Itching to get out again, second exploration tour: Reach the roof. Did go as far as the Cobra could take me. Five hours there and back. Space is very black up there.
5.) Took a short break and did some rares and regular trading and NAV/RES-BH so I could finally afford an ADS. Went for my first...
6.) ...multiple-session exploration. Took a decidedly touristy 4-day-route to Witch Head, Orion Nebula, Gamma Columbae (okay, maybe not that touristy), Pencil Nebula, the Musca Dark region near the Coal Sack and returned home. Put my name on a lot of stars during the Orion-Musca leg, but it was more of an endurance test than anything else. Learned that I have severe difficulties leaving my ship out in the cold for the night. Every log-in was a little moment of "are you still there?". Got into the habit of parking in planetary rings.
7.) Decided to take it slow and work myself towards an Asp. Started to get interested in the local background simulation and decided to run along with it. Bought a T6 in addition to my Asp for some nice and relaxing (and profitable) trading.
8.) Saw the Lambda Andromedae community goal.
9.) Did way too much rares trading. Not doing that again, can't get any fun out of it.
10.) Got into the top 70 percentile at Lambda - real life cut my ambitions for the top 40 short - and bought the Discount Asp. (Said goodbye to my T6 when collecting it.) Brought her home.
Current situation:
11.1) Am a few millions short of the exploration ship I want to make out of her. Do not care right now. Simply having fun with the beast - just playing the local background simulation, trading, doing missions, boosting inside the station for the sound of it. Sometimes taking the Cobra out for long-range activities. (The A5 FSD for the Asp is among the few millions I still need.)
11.2.) Have a time limit for getting the Asp ready for extended exploration: I want to leave one week after the official Wings release.
Future:
12.) Pilgrimage to Sag A*, after that, go North-East and than follow the Perseus arm widdershins to its very tip. Will then try to jump the arms inward and reach Alnilam on my way back home.
Already got way, way more out of this game than it and the cheap HOTAS I bought for it cost me. Still can't find, for the life of me, anything that's frustrating. (The absence of QTEs might have something to do with that.) The fact that Elite Dangerous is not very accessible for casual gamers is not a statement about its quality, only about it's target customers.
