Variant humans remain the same (floating +1/+1 and a feat); standard humans are boring and I don't want to think about them; for races with modifiers, I'm pretty happy with the current net modifiers, but adding penalties so you can have larger mods. But in addition! racial modifiers (except for variant humans) also affect minima and maxima: if elves have +3 to Dex and +2 to Int but -2 to Con, they can get Dex 23 and Int 22 but only Con 18. If half-giants have +4 to Strength and +2 to Con, they can get up to Str 24 and Con 22, etc.
When I was thinking this through, I thought that it might make more sense to go with half the bonus for improving the maximum. Then if you had a race with +20 strength, their racial maximum would be 30.
Then a Storm giant with a racial bonus of +18 has a Strength maximum of 29. It solves helps soften the blow when you hit the 30 ability score ceiling... Just a thought.
