It can be.Is the race of a PC the main thing that distinguishes one PC from another the only thing that matters? Combinations of race/class/personality/goals/setting/etc don't mean anything?
One of my favorite PCs was a half-elf and his whole personality, outlook, attitude, and class choice was built upon half-elven tropes and subversion of them.
It's not automatic.Why is a DM "uncreative" if you can't possibly have more depth to your PC than "it's an elf so it's exactly the same as every other elf I've ever played"?
However if your world is a clone of another with the names scratched off... that's the definition of uncreative.
