In all honesty, I didn’t think there was one, because I didn’t think they would win.

Not to say they didn’t “defeat” the game or anything. But in my mind, I assumed that the game was eternal. When when a null session was created, it would just perpetually trap them within a time loop to repeat the game without ever realizing it. And if they won…well…the loop would still happen. They would be sent back in time, or transformed, or something, unable to escape.

Like, there was never an end. The purpose of the game was to keep them trapped in the game, to keep them in that loop forever because they can. And the whole point of Homestuck was to see the kids break out of that loop.
