The opening, "
The Gone World is a rules-light ttrpg. What is a rules-light ttrpg, you ask? Google it. Stop playing games and start playing games!" is kinda a little offputting? Like, I get you're trying for a cheeky tone, but it's apt to turn players away.
I really would like to see stats expanded on. I'm having a hard time internalizing how skill challenges come up and how they are overcome with this.
The Phase structure is really cool though! Great themeing.
