IGN has an article written by Jeff Vogel about the trials and tribulations of being an indie game developer. His company, Spiderweb Software, has written a number of RPGs you probably won't find on the shelves of your local game store. One observation he has is that elves sell better then celts:

I did actual historical research, with books and everything. I read about Romans and Celts, their lives and their beliefs. Within the limits of my puny budget, I got authentic-looking art. I had a cool scene of Druid human sacrifice, adventures in the land of the dead, and all sorts of freaky faerie action. I paid a quality artist to do an awesome painting of a Roman kicking a Celt's ass. It was a really cool game.

And what happened when I released it? How were sales? Well, in gaming terms, I got pwned.

The article's a bit short and fluffy, but interesting nonetheless.
