I often wonder who uses the A* code. Sometimes people write to me to tell me they've used the code in their University assignments or just for fun, but has anyone used this in a project that I don't know about?

My A* algorithm on google code

During my time at Activision I worked on a code base that included some code from their game Gun, and was happy to find my code, verbatim included there too!

Also, today, I downloaded a 2d game prototyping engine called Angel, from some EA guys. When I looked at how their path finding worked, I was surprised to see my code in there too!

It's cool that people are using this code. If you do use it in some commercial or interesting project, please let me know. A credit or thank you in your product would be nice too!
