I minor correction for your description of Stamina, Fred:
The 10 minute recovery is only if you spend a resolve point.
Otherwise, all SP overnight, level HP per night.
Given that HP don't appear to go up per level...
I've looked through it, mostly at CGen...
Start with all atts at 10...
Pick Archetype. Gives a feat chain at 1/6/12/18th levels, and +1 to an attribute.
Pick race, which adjusts 1 or more attributes ±2, grants one or more feats... it also provides 2, 4 or 6 HP.
Pick class. It determines class skills, gives a feat or two at level 1, sets skill points per level, stamina per level (fixed, no die roll option; Con Mod applies) and HP (no con mod), both in the 5-7 range by class.
10 points to spend on attributes from there, to max 18.
So PC stat range is 8-18, HP is 7-13, and Stamina in the range 4 to 11 per level...
PC stats look a lot like a slightly muchkin version of 5E's stat range.
To me, it looks very much like 40K meets Pathfiinder 2E...
Note the conversions in the back for Elf, Dwarf, Gnome, Half-elf, Half-orc, and Halfling... I expect a revised Pathfinder if Starfinder is well received...
