[Star Wars] If Obi-Wan was killed at the hands of Darth Maul during their battle in the Phantom Menace, what would the Star Wars universe look like from that point onwards?

This is effectively an alternative history for the Star Wars universe. How would the events of each episode go down differently due to the defeat of Obi-Wan? Would the Jedi be extinct? Would the Empire ever fall/come to fruition in the first place?

Assuming Qui-Gon also dies, Anakin is left stranded on Naboo. Sidious would probably order Maul to bring Anakin to him, and he would be trained as a Sith Lord. 

If Anakin reaches the others before Maul gets to him, they leave to go back to Coruscant and the Council refuse to train Anakin - it was only Qui-Gon's defiance that led to Anakin's training at all. From there Anakin probably gets picked up by Palpatine directly - he has tried to make Anakin leave the Jedi Order before, in the comics.

Either way, Darth Vader is coming much sooner than expected, and much more powerful than before.
