Long post ahead. There is a TLDR at the end if you don't want to read the whole thing.
I've done almost everything the game has to offer, except for rngineers and deep space exploration/ruin hunting. I've never made the journey to Sagittarius A or Colonia.
I started the game in Gamma, playing in Open. I watched some twitch/youtube videos to try to figure out what the best way to progress would be. At the time it seemed to be bounty hunting (though I'm sure in reality it was something else that I wasn't aware of.)
I made it into a Viper, then a Cobra. Continued bounty hunting until I had a Vulture. In the Vulture, I got blown up by another player while in a CZ. I had put at least a couple of hundred hours into the game by this point, but I didn't have enough credits to rebuy my Vulture. Fortunately, I still had my Cobra from before so I wasn't starting over from square one but I did lose a lot of progress.
After that, I took a break from the game for probably at least 6 months before trying to do anything else with it. He got me fair and square, but I was the dummy that flew without a rebuy,
Picked the game up again and did bounty hunting to get a type 6 to do cargo runs. Also tried my hand out at mining. Traded my way up to an AspX. Once in the AspX, I heard about Robigo and went to check it out. Easily the most fun I've ever had in this game. Then they nerfed the hell out of it. I made enough from smuggling to get a Python. I was pretty tired of bounty hunting by this point so....back to trading. Traded my way into a Type 9....but I didn't really enjoy losing access to medium pads and having an even more anemic jump range than the Python...so I went back to Python trading to save for an Anaconda. I did about 60 million worth of trading routes at about 2-3 mil per loop and kept checking to see how many more credits I needed to get an Anaconda and at least A rate it's FSD.
Then about 3 weeks ago, I kept hearing about Quince. I finally decided that even with the Python's anemic jump range it was worth doing the 30 jumps to check it out.
I started doing the surface scan missions, and made a few million off of those. But then I kept hearing, passenger missions are where it's at. I didn't see a lot of passenger missions at Millerport. So I decided to check out Jefferies High, and the rest is history. In one day, I went from 80 million short of buying an Anaconda to heading back to the bubble to get one.
I came back to Quince in my Anaconda to do passenger runs, but after making about another 100 million this way I decided I wanted to try the surface scan missions again, even if they were nerfed.
So I outfitted an Eagle and have been doing surface scan missions ever since. Even when you can only get 3, some of the missions pay over 2 mil. It's probably less credits per hour than running passengers, but it also isn't boring me to tears either.
I even decided that since I don't give 2 bits about losing the Eagle that I would play in Open. I really enjoyed the risk factor of the Robigo smuggling and I thought playing in Open might be a way to bring that back. I got interdicted once by an Adder last night, and ran because my eagle is outfitted for cargo, not combat, thanks to having to take the random junk some missions reward. Even if I was in an A rated rngineered to the teeth Eagle I probably still wouldn't have engaged him. I fly with a Logitech 3D Extreme joystick, so I'm at a distinct disadvantage to players who have a HOTAS, or those who use KB/M, to do FA off and easily use their maneuvering thrusters in combat. He got me down to 7% before I jumped. The thing that sucked is that I had already gotten close enough to the planet to get the search areas in SC. I didn't know I would lose them, and have no apparent way to get them back if I jumped to another system. I had a lucky board so I had to abandon 10 missions, which the factions weren't too pleased about.
TLDR: I'm doing Quince because I have already spent hundreds of hours in this game doing other things. I would like to build up my credits so that lack of credits is no longer an obstacle to try any ship or loadout that I want. I also want to rank up in the Empire to get a Cutter and this takes care of that as well. I'm not going to go back to trade loops or regular missions that require more effort to complete and pay much less.
I don't recommend new players going to Quince because they really don't need payouts that high off the bat. In my opinion, they should take their time (say maybe 100 hrs worth of playtime) learning the game and trying every playstyle this game has to offer that appeal
