i want to creat an ARG

if you don't know what this is there the definition ; An ARG (Alternate Reality Game) is an interactive investigation or treasure hunt that takes place simultaneously online and in the real world. The principle is to blur the line between fiction and reality. ( I found it on internet) I looove finding news arg or old one bc I feel like an kid from the 2010s on reddit and I found that so cool. if some of you are intersested I can found some arg and tell them to you. anyway I want sm create an arg but idk where to start I am gonna work on it then maybe in two years you gonna know abt it... if you have some ideas Im interested :)))))
