Depends ... Logicaly Humans dont get [Elf] dialogue options and Elves dont gets [Human] dialogue options (wich are BTW incredibly rare last time i checked).
Other than that ... Cant think about any difference that isnt also some mechanics. :-/
Humans obviously dont see in the dark ... Elves might have a problem when NPC wants to put them to sleep in dialogue.
I still dont understand why cant we change Race for our hirelings. Lets us play Githyanki as racist as they trully are!
