me personally in regards to the question of “how could SBURB be so cruel doesnt it want people to succeed” is that nowhere in canon has the alpha timeline nor sburb as a game ever stated to be sentient or indeed anything more than a humble programmed disc. noras it ever been stated that it wants players to suceed or fail
its cold and calculating because its just a machine, it doesnt think. the programming just. generates a game based on the players. why else all the stuff about death? why else would dave get a planet secifically created it would seem to traumatize him? because the function of the game is personal growth and it throws the solution to your life problems at you like straightforwardly dunking you right into a pool to teach you how to swim. i mean. sburb never tells u or promises u anything good or bad it just auto generates an environment and npcs to play a game based on your psyche. thats all its ever been called is a game. why else would it be clearly stated that most sesions straight up fail. heck even the canon sessions had unkillable glitches dooming then and they all techically failed in some way. why would it let LE exist at all in the first place? who does that benefit other than LE?
the only aswer to me is that it doesnt let anything happen or not happen. it just is
and when you look at what it actually is from a programming point of view, everything really does make sense and is easily explained by core programming and computer functions
i dont think its really a stretch to view sburb as just a mindless programing pumping out commands as the game is played. and eerything else in homestuck is played straight when it comes to parts of realities being mere game constructs
i think its a far greater stretch to assume that the sburb game has any kind of sentience, even moreso a benevolent one when not a single line in canon suggests this and far more comments by hussie suggest that it really is just a game
