First idea: This sounds really intuitive, I like how you put into consideration the factor of being offline or not. Keeping the factor of offline as instead the users maybe ‘returning home’ or commuting somewhere, while not very scientific or set to a pattern it works in the sense that it’s humble and that they can always return. Sort of like:

The concept of inactivity or being offline can have it’s own story basically depending on what might happen, if a user leaves they complete leave the universe using some kind of inter dimensional travel or something in which overtime they also have their characters / them as remnants left in that big desert at a certain location.

Arcion and the trail to shock I have no idea what those two entail, like the room and the Arcion catalog, I don’t know what that is so I haven’t got much to say there.

The eyes of Jim actually sounds really neat like a sort of abandoned robotic part area just left dormant in space with some kind of connection to Jim that would ‘watch over’ the people of Stick Nodes. This idea could also be tied with perhaps the idea that certain aspects or stickfigures could be an abandoned part of the SNU left to float around endlessly or to just be left dormant on other planets. We could probably come up with something there..

The concept of a higher power sounds really cool and I think there’s definitely potential with a kind of ‘SN Religious Figures and Deities / Gods’.

Overall really nice work man, I love the ideas.
