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
