Who wins?
By entire, I mean EVERYTHING. Halo, for example, would have all of the Precursors, Forerunners, Covenant, Flood, and Humans all teamed up against ALL the Star Wars universe
They all have their technology as well. Halo has their Halo Rings and such, Star Wars has all their Star Destroyers and Death Stars and all that

Meh, people clinging to Halo in all these forum questions always fall back on the Flood or the Halo rings.. it's clear your beloved Chief couldn't go too far outside of his comfort zone.
