Didn't it work out to "you were stopping yourself the whole time"

Again, yes and no.

Like I said, in the original timeline, the emissaries from the future fail to stop the player from creating the time machine, and this allows the time loop to proceed forward.

Of course, when Future Bing eventually sends the player back, the player actually succeeds in stopping the creation of the time machine.

So this presents two opposite outcomes of the same event, meaning they can't possibly exist with the same reality.
Another thing to note is that the player may not have been among the emissaries who fail to stop the time machine's creation; they may have all simply been the poison-weakened residents of the future, which would explain why they succeed in the second reality (since the player, being from the present, is supposed to be much stronger).

I think the timeloop was destroyed though, because Bing has his memory wiped.
Pretty sure the MST3K mantra should have been the motto of the whole event.

Yeah, the time loop definitely gets destroyed.
I was just saying that this shouldn't have been possible since, being a loop, every event is required for the next.

I think the black hole generators Future Bing gives you were supposed to act as an anti-paradox device though.
Of course, assuming the existence of such a McGuffin, Future Bing could have broken the time loop by breaking any one of the events in it, including stopping himself from sending the Visitors back in time in the first place.

Why can't all fiction work time like Doctor Who?
