Hi there! Thank you, I'm really glad that you like it!
If you check the top of page 11, I mention rolling 3d6 for each attribute in turn (3d6 down the line - STR > DEX > CON etc.) This will generally result in lower attribute scores than in more modern versions of d&d, but also they have slightly less mechanical impact too..
I'm hoping to release 1.0 soon, I just want to make sure I've got all the wrinkles ironed out.
