I'm confused - is this not just a slightly modified version of point buy, where the ceiling is higher and you have way more points to spend (for RAW point buy, N=27)?
It is, but I mixed two descriptions in my writing : one is {8-everywhere + 27 Purchase Points} and one is {75 Purchase Points but you can't end up with less than 8 in any one Ability Score}. I've updated the description. (Also, N=75 was made up on the fly, it could be 70 or 80, the question remains about the same.)
