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

Well no shit star wars have completely unrealistically powerful weapons which the typical 12 year old nerd comes up with "OHHHH HOW ABOUT A THING THAT BLOWS UP LIKE 5 PLANETS AT A TIME" not to mention that starwars has films that explain everything while you gotta search up more info on halo (which I really doubt the typically starwars fan would have pleasure doing).
