Ive seen lots of people with dragcave in their sigs. Are there any other games that people play besides dragcave that require putting in your signature or else your doomed?
Personaly I play mybrute and dragcave. you can go to mybrute by clicking on my sig, and everyone (or nearly) has seen dragcave. What else is there?

If this is a topic just so people can click on each other's eggs, this will be closed.
