[quote]The "weird forerunner thing" that can kill everyone in the galaxy at the touch of a button. Including those in the death star, as the Halo side shelters on the ark. Sorry.[/quote] Comparing that to the deathstar, Halo definitely wins. But comparing it to ALL the doomsday and super weapons developed in Star Wars [spoiler]centerpoint station, sun crusher, galaxy gun, etc.[/spoiler] then I think it might be a tie Overall, I think Star Wars would win because of the sheer force of characters, races, and powers found in that universe. Don't get me wrong Halo has it's fair share, but I think Star Wars is more developed in terms of just background information on the universe's history
