Gamers handbook to the IRL game

If this would have been an item in the physical world, it would have been a book. And if you would pick that item up, you would be able to read something on the back of it. Now, since this is not a physical book, it is"just" an ebook, it has no back, thus, you cannot read anything on it. But even so, here it comes:
 
This game you are currently playing, the IRL game, have you ever found any walk-through, rulebook or found any comprehensive guide online?
 
I have not.
 
So, based on my own game-play-experience, I will break down the game as best as I can, and give you my perspective on it so far.
 
Speaking of perspectives. There only seems to be three rules in the IRL game that applies to every player.
 
 1. The only truth is that there is no truth.
 2. All choices, and non-choices, come with a consequence.
 3. The only constant thing is that everything is constantly changing.
 
Well, I just gave you the three biggest keys I've found so far. If they do not make sense, read the book and hopefully they will make sense. Or, perhaps, you will end up with more thoughts and questions than before you started to read? Who knows? Nobody knows! Or Whose nose? Nobody's nose, as Muddhedd brilliantly put it.
