You were pioneers on this path. There was a romance in it. Now, doing what you did back then is like discovering a place where no human has set foot. I envy you! And thank you for the beautiful games)

Autolycus. Now that's a name I've not heard in a long time. :)

It's always nice to hear from someone from "back in the day"! Working with the developer community during that time is one of my best memories. So many people from that time have made the jump from amateur to professional game developers. I love seeing people who kept following that path!

I can't give any official answer as to whether you could use Hammer or FGD files for your own game, but I don't see why not, assuming the FGD is of your own making.

You might try going through Steam support to see if you could get an official recommendation.
