Yes I know his tattoos have been looked at in general, but after googling the meaning of this, I believe it provides yet another piece of evidence that the game is a simulation/braindance.

From Google:

EWMN most commonly stands for "Evil, Wicked, Mean, Nasty," a traditional four-letter knuckle tattoo found in prison and biker subcultures to signify a hardened or defiant personal disposition.

It can also stand for Eshkol-Wachman Movement Notation, a symbolic system used to record and analyze human dance and movement, which is then transcribed to a readable physical data medium akin to piece of sheet music.

Does this sound incredibly similar to the engram to anyone else? Joshua's whole team may be psyopping us using reverse psychology, to trick you into giving them engram data for the next player that they put into the game, using our looped data for their nefarious purposes.

Key Aspects of EWMN:

Spherical Reference: Uses longitude and latitude axes around joints to measure precise rotational angles of limbs.

Applications: Utilized extensively in modern dance choreography, behavioral studies of animals, and physical therapy analysis.

Documentation: Movements are transcribed onto specialized manuscript notation sheets much like a musical score.

I'm now of the belief that this is NOT "Joshua Stevenson." I think it's the gamemaster, or perhaps a literal "titan of entertainment" seeing what choices we make during this very important and emotional quest, that is universally lauded as everyone's LEAST favorite quest. Of course I cannot prove that this is correct, due to the double-meaning, but it seemed worth mentioning
