SaintsSinners, Thank you very much for these tutorial. I tried to create my own customised mod to play but do not know how. Borrowed books on sql and xml, and read the basics. Tried creating the mods both in xml and sql format but was unsuccessful. Then I came across this discussion and found a great relief. Thank you very much. I have not started your tutorial yet but surely, this informations is what I needed. I have purchased SQLite from AppStore recently. Do we need SQLite Studio specifically to create the mod.
