Wow, I haven't heard about AGS for a while - glad to see it's still alive and well. It should be noted that it's open source and still sees regular updates (20+ years later!)
I remember the original author of AGS was strongly against open source back in the day. Nice to see he either recanted, or handed the reigns to someone who wasn't opposed.
Wow! 1999? I know I'm old when it feels almost like yesterday... (I knew it wasn't a recent development, but I still remember when I first heard of AGS as if it was yesterday!).
