I admit it – my favorite PC by far is a good-aligned drow.
This makes me a horrible gamer by some Internet standards. If you look around at various D&D and Pathfinder forums, you’re sure to find at least one or two threads lamenting the existence of good-aligned drow. There are even quotes from Gary Gygax talking about how he dislikes the idea (although, to be fair, there are also quotes from Gary Gygax talking about how if you change even one single rule in your game, you aren’t playing D&D).
The existence of good-aligned drow became popular thanks to the success of R.A. Salvatore’s novels featuring Drizzt Do’Urden. Because of that very success, a lot of fantasy RPG purists out there tend to see any non-evil dark elf as nothing more than a Drizzt clone.
I would like to speak in defense of the good-aligned drow in RPGs.
