Well the topic was the whole of Halo vs Star Wars didn't realise it's a game only thing. As for the force thing that's cherry picking it's clearly shown and was canon and seeing as no contradicting canon has been put in place of it it still stands. Seeing as the Forerunners alone had 3 million worlds trillion/s is not a far off number especially after adding in around 663 sheiks worlds with production plants numerous space stations both in and outside of slipspace and then add in all of humanities and the san'shyum sits not a hard number to reach. Meh neither Promethean's or Armigers (as far as is currently known) are to difficult to destroy but it's their sheer numbers that overwhelm and destroy the enemy. The Halo universe is quiet barebones until Hlao4 and the expanded universe of Star Wars gets to use it so does halo.
