i mean, part of the point of sburb is that it's so complex it cannot practically be a real game, and that's not just in the sense that something like alchemy can have endless possibilities, the game itself is needlessly complicated by design. like half of the devices in sburb just complicate theoretically simple processes for no reason.

that being said it's not that sburb cannot be simplified into a real video game - it totally can, it's just that it will take a lot of resources to make for what is largely a pretty generic end product, like sburb in its conception is a bunch of quite typical video game elements stuck together. i think the appeal of a sburb video game is overexaggerated, like in the comic the whole client-server relationship is cool partially because it happens in the real environment and the impending doom is something that you get to witness as the audience. imagine if you were playing a real video game and the fact of whether or not you get a game over before even starting is whether every single one of your friends you're playing with managed to deploy all the shit their client needs on time and in convenient enough places for everyone to enter on time. and if we follow the events as they happen in the comic, it all must happen one by one, meaning that the bigger your session is the more time you'll spend just waiting around. and that's not even getting into the fact that in this setup it's entirely possible that you enter first and make significant progress in the game, only to find out one of your friends fucked up the entering so all your progress is lost and you have to start over.

this, of course, can all be worked around, for example you could streamline the entrance process or cut it out altogether, but then what you're left with is the actual process of playing sburb - which is so filler even the comic basically doesn't show it. even the process of building up your client's house seems like a mindnumbing task in practice - imagine if you have to halt your entire adventure and personal quest every once in a while to sit and spend like half an hour playing sims build mode except the only goal is to build the structure as tall as possible. the meat of sburb seems to be exploring dungeons and killing enemies, which is never fully focused on in the comic, so the game would need to basically be made from scratch and probably be yet another action rpg which is vaguely homestuck themed.

my point is it's possible to make a sburb game, but either you keep in all the iconic elements of sburb from homestuck and make it practically unplayable, or you streamline it and make into a pretty generic action rpg with maybe a few homestuck gimmicks which will probably take too much resources to make for the ultimately niche audience it'd be filling.

either way i don't see this being a realistic project, especially not in any foreseeable future.
