@Kaethra:

Variety is king, though. Take World of Warcraft, for example; sure, Humans and Blood Elves are the most popular races, but even together, they make up less than half of the total population. Worgen have proven to be exceptionally popular, for example.

"Pretty", Human-looking races will always be the most popular races, but if you're someone who wants to play that, then you're already got three different races that cater specifically to you, and Yugiri's race will probably make four. Frankly, the game *NEEDS* a bestial, inhuman Race if they want it to expand, so that no matter what your particular tastes are, there is (most likely) going to be a race that appeals to you. If all you have are pretty, human-looking races, then you're not going to attract anyone that isn't already playing the game.

It might not be the most popular race in the game, but having variety is important.
