I like the Grey Elves from my campaign. They are the keepers of knowledge, very stoic and serious. The only wizard I truly enjoyed playing (I'm primarily a kick-in-the-door fighter type) was a grey elf that was trying to find the secrets to lichdom not for any nefarious purpose, but to simply be able to live beyond his years an continue to learn even more spells and attain all the knowledge that he can. Sadly, his one time friend and King of the region saw his attempts as an abomination. They slew each other in an epic duel that saw to the end of the kingdom and peace.
Since I've been playing WoW, I'm starting to like the look and ideas behind Night Elves. Very cool.
