I thought I was doing something at lvl 57
If youre on pc, I would suggest you build an outpost in a zone with aluminum and one with iron. Maybe you can find a place with both. I got lazy and have two instead of searching for a place with both. Bang out sessions crafting adaptive frames. I go to sleep on the aluminum planet for 24 hours and fill up a shytload of bins, then fast travel to the iron planet and craft frames for like 5 minutes. Usually pick up 2-3 levels a cycle. Go sell the frames for money at trade authority. I prefer selling them in the Well on neon bc 24 hours local time will reset the vendor's cash. Then if I have more than they will take in one go, I sell off the remaining ones.
Basically I have started buying guns and suits for free now lol. There's a lot of videos on YouTube about how to do it and I usually stop when I have more points then I can spend because you have requirements to rank up skills.
This crafting stuff normally isn't my thing but I decided it was worth the 2 hours I spent making it. I'm not normally into a game like this because crafting isn't my thing at all. I prefer to be fighting in space or chasing down some Spacer Scum, but this is the fastest easy way to gain xp and money without doing much. I didn't start doing it until around level 37.
I go play the game normally and then when I get bored or just need some money, I go to the first base where time passes faster and go to sleep. When I wake up all my bins are full. The outpost is on a low gravity planet so I can just use the boost pack to collect all my items from each bin. Then I fly to the second outpost with all the iron, walk into the outpost and make frames for about 5 minutes. It's pretty easy once you get used to it.
One thing I really enjoy is how much variety the skill tree allows you to have. I had to put a lot of points in tech but now many things are easier for me to do.
