Likewise! I played a ton of Graal Online during my adolescence and owe my programming career to its level editor (NPC scripting). I was able to learn how to program without reading much documentation outside of reading its command sidebar and inferring from others' NPC scripts. Thinking about it now, they did an outstanding job making it very straightforward to learn and use.
It's sad to see it go. I really wish we could have a game experience that had the community graal did. There's not much with that level of involvement for players anymore; it's all now downstream of ivory towers and extremely restricted.
