Earth C could have been interesting if anyone had bothered to take it seriously as a setting. Unfortunately it seems like the canonical Homestuck 'brand' will always be marked by this sort of Peter Pan-like refusal to engage with the idea that there is a real world anywhere outside of the video game constructs that form a pale backdrop to Character Interactions. You see this not only in Homestuck proper, where it makes sense because those Earths are basically dead on arrival, but in Skaianet Systems, where history itself is relegated to a game of like 'plug character name in' Mad Libs.

Abstraction can be fun! But I also think that being afraid to write anything except pure farce almost feels like playing on easy mode, staying in a comfort zone, refusing to take on a challenging writing concept just because it's challenging and would require thought in order to make interesting stakes and plot threads.
