I find it interesting that, in every world setting I've ever seen, humans make up like 95% of the population, yet before 3E came out, almost no one ever played one. Then, when the rumors started that 3E was getting rid of Racial restrictions like level limits and class restrictions, people started saying that the problem would get even worse and no one would play humans anymore.
And now look. The number of people who have played Humans in their game, as of right now, outnumbers the number of every other race by more than two times. I have to admit, I play mostly humans as well. I have played a half-elf, and elf, and a gnome, but those were all characters created in 2nd ed. and converted over. I think the only non-human race I have created since 3E started was a swashbuckling halfling rogue named Figgiwish Merriboots (possibly my favorite character that I have created in a few years).
