I ask this because I recently started playing Baldur's Gate again (I had to start over because my old save game was lost). One thing I noted was that no race received ability modifiers (aside from dwarf/elf max con/dex weirdness). I mean, putting aside all the dumb class limitations for races, ability modifiers did not dictate what classes your race was pigeonholed into.
And I mean really, what class guide doesn't give human an automatic blue rating and half elf/orc at least a green? Lets not mention the damned Aasimar/tiefling variants either that let you basically custom pick your ability scores.
It just seems like to me if we could do racial variants for all races (or hell, could at least alternate attributes like 4E did) we could come up with more original characters. I mean, there ARE people who do it (like a friend of mine who rolled up a gnome paladin) but it would be nice to not be mechanically punished for trying to do so.
