This comment brings me so much joy. Ultima Online is my favorite game of all time, having played since T2A (I was nine years old at the time). I have fond memories of hacking away at my own shard, cobbling together scripts and editing MUL files (a custom file format that the game used to store binary content) to add new creatures and items. My first exposure to "programming" was SphereServer, which used one of the worst scripting languages I've ever written in retrospect. Later I took a stab at C# with RunUO and while my attempts never manifested into anything noteworthy, they did establish a foundation for the career in software I have today. It warms my heart to see kids embracing this sort of creative spirit for games like Minecraft. The modders of today could be the engineers of tomorrow.
