This is just a post of sheer curiousity, and might be getting a little personal, but here goes: What was the best game you ever made? How much did you make off of it? How many customers did it bring?
The more stories, the better.

Note: I'm not gauging anyone's experience on my own, or setting any expectations based on everyone's input. It's just nice to see some good success (or failure) stories.
