Every now and then someone suggests UnReal World to be made fully moddable. That would mean essentially re-writing the engine of the game, so not going to happen. But with Ancient Savo I got to start building from scratch, and wanted to experiment with modding built into the core of the game engine. I started with a rather modest approach, but as often happens the needs and the ambitions have been growing as the project goes on. Now it is becoming a modding language written in XML files; it has variables, built-in functions, and simple control structures like IF and GOTO. (But the syntax is still somewhat vague, as everything grew somewhat dynamically instead of me strictly planning everything beforehand, so I have also been experimenting with different ways to write the modding script.) Depending on Ancient Savo reception, I think one of the possible future sequel projects would be a full survival game construction set with GUI tools to edit items, actions, menus and stuff. But let's see how it goes =)
