I don't suspect many people will find this realistic or entertaining in the least given the record of accuracy, but keep in mind that your own creativity will lead you to far off places.
First let me give you a link to the definition as to what an ARG is as defined by Wikipedia. https://en.wikipedia.org/wiki/Alternate_reality_game
Once you see what one is, its good to notice that Alice & Smith are quite popular right now with their Black Watchmen, Ahnayro, and Secret World Legends games. All of these games lead to real world research. Less in SWL, but they are Alice & Smith and worth a mention.
What happens inside these games will send you on a journey of discovery of one thing leading to another creating a fantastic narrative that will make things that have nothing to do with one another intertwine to create a great story.
If you can't tell I'm quite a fan of these types of games and they are a great respite from the every day humdrum activities. Many people on YouTube try and create them as well. Often times they use the Slenderman as an example. These can trick you into believing that what isn't, is real.
How does this apply to Qanon? Well, with the cryptic and small amounts of information given, everyone is forced to research and speculate the information and can communicate with one another just like an ARG. When the infomation is released in full by MSM, the researchers and speculators naturally tie together the small amounts of information to the past information given to them.
This is not a conspiracy, but I do believe it to be a hoax. A game. A person puppeting as many people as humanly possible. Someone saying, let me drop as little information from the past as possible and some made up and I'll see how many people I can get to stick around and bite.
I believe they call it LULZ when its done for fun. That is if in fact this person is an Anon in the first place. Its from my experience that they aren't quite so cryptic and are more up front and deliver information to the layman.
However, I could be wrong and would happily apologize, because if it is in fact true it is useful information. Though my beliefs I am currently holding true to. I have yet to see any real evidence that holds anything more than what I've done in the past in games and in my own trials as an attempt to create my own. I just happened to use music and movie clips.
Good luck finding truth wherever it may be and I hope that you aren't wasting your time with this, but if you are...
I hope that you are going to discover something useful and worth your time spent researching very few words.
