Nice! I'm level 31 and these are my skills:
4 - Stealth
1 - Theft (from my background)
4 - Research Methods
2 - Surveying (I think I will level this up, surveying planets is super chill)
3 - Spacesuit Design (rank 4 is useless as it doesn't unlock new stuff, just makes it so crafting is free from time to time)
4 - Weapon Engineering
1 - Outpost Engineering (I just dipped my toes into outpost building, I think I'll love it so more skill points will follow)
1 - Special Projects
4 - Piloting
3 - Security (same as Spacesuit Design, rank 4 is largely useless)
3 - Starship Design
As you can see, I spend exactly 0 points in Combat skill tree. I play on Very Hard and I find it still too easy, so spending skills there is just a waste as they don't unlock any new 'gameplay' possibilities, it's just a damage multiplayer.
Also, 0 skill points in Weight Lifting and I can easily achieve 245 carrying capacity so that seems to be a waste to as it doesn't unlock new possibilities like in other Bethesda game (for example: run when over encumbered etc.). But maybe once I level other cool stuff, I'll dump some points into it.
I have 2 skill points banked and I'm now thinking where to spend them!
