Five free ranks in any skill. That must be Favored.
A +10 bonus to any one skill. (Which may or may not be one of maximum three allowed.)
A five point discount on a 20 DP Talent. That most characters only take once, if at all.
HARP Sci-Fi offers the same deal, except they allow Professional Adaptability to be swapped out for the ability to treat a single non-Favored skill as if it belonged to a Favored Category.
Humans may get the lowest stat modifiers of any PC race in the game, but they make up for it in their ability to assign those modifiers as they see fit. Their racial talents, however... there's nothing to be done with them except to immediately take Blood Talents to replace them.
I've been considering something.
What if we combined Bonus Skill Ranks with Skill Flexibility? Humans gain 5 free ranks in any one skill, and that skill would always be considered Favored for them, regardless of Profession.
Skill Specialization is great as long as it doesn't count against the three Skill Specializations a character is allowed to have in his life. So it doesn't.
And Professional Adaptability. Instead of giving them a 5 DP discount on a 20 DP Talent, give them the 20 DP Talent. At 1st level, they pick out their Culture and their Profession, all of their Professional abilities and all of their adolescent ranks. Then, before they spend their DP, they pick a second Profession and gain one Professional Ability from it-- as if they'd taken it at 2nd level-- and for 1st level only, they can purchase skills as if all of the Favored Categories from both Professions were Favored. Starting at 2nd level, they can advance in either Profession, one Profession at a time, as normal. If they want to pick up a third Profession-- which I have never, ever seen a character do-- they can purchase Additional Profession again at the full 20 DP cost.
