I'm thinking that Sburb is actually meant to contain Lord English, as opposed to acting as part of his grand plan. While Sburb has seemingly gone on for many iterations, there doesn't seem to be any evidence of any players outside of the kids and the trolls, and I'm thinking this is a point of notable mindfuckery. You see, I'm speculating that there AREN'T any players outside the kids and trolls, that the two worlds are being used by Sburb to fulfill an ulterior motive.
What I'm getting at is, Earth and Alternia are connected via stable time loop, once the kid's supposedly lose their game, Alternia ends up getting created, the trolls lose, and then time loops back around and creates Earth again, where the loop repeats. In this sense, Alternia and Earth are in eachother's past and future, and that this is exactly what Sburb was originally created for. With the entire universe trapped in a stable (unstable?) time loop, the universe will never die, and if it never dies, then Lord English remains trapped forever, which is why he hasn't made his appearance yet.
Point of order, because nobody commented on this. The games we've seen
are not the only times the game has ever been played. Or at least, Karkat claims as such-
CG: REALLY THERE'S NOTHING MORE TRAGIC THAN THESE NULL SESSIONS FULL OF KIDS ENTERING THE GAME AND FULFILLING SOME COSMIC DESTINY SHIT JUST TO GET WIPED OUT AND LEAVE BEHIND AN EMPTY POINTLESS INCIPISPHERE FOR ALL ETERNITY.
CG: ACTUALLY IT'S SORT OF HILARIOUS.
CG: OR IT WOULD BE IF IT DIDN'T AFFECT ME PERSONALLY.
This isn't the only game the Trolls have ever looked in on. Probably, Sollux found it when back-tracing whatever happened to their game. But somebody thought to look in on other games and see what it's supposed to look like; this may not even be the first game they've fucked around with. They may never even have found a game that actually played out successfully.
Something to consider. Sburb was supposedly a Beta, from somewhere. Sgrub was pieced together by Sollux, noted hacker and virus master, from hieroglyphic code he found. The hint I'm getting is that nobody has played the game the way it was intended, by whoever made it, because nobody's working off a complete finished version.
I'm waiting for Aqizzar to comment on my new thread title.
Think rather highly of ourselves, don't we? Besides, we say it
because it's true.
