Some players achieve CHIM, but only those who are modders.

Screenshots: Say that players don't have the power of CHIM
Comments: Say that the explanation is too complicated, and that CHIM is the power the players have via the console, modding, the construction set, etc.

No mate, the explanation isn't "too complicated", the two explanations are in direct conflict.

This is...

ten thousand times more complicated than it needs to be. "CHIM" is just every way a player can affect the world from the outside via modding tools or even things as basic as saving and loading.

Very good

Basically, Pc players that use the creation kit to alter the state of the world have "achieved CHIM" with their character.

so basically it's the Matrix

This is...

ten thousand times simpler than I could explain it. I remember seeing a theory that CHIM was the same as the player- pc relationship. Console commands and mods being the reality control, the PC being Anu (the Dreamer), etc.

Very interesting, but I like this nonetheless.
