Halo is cool, but I like Star Wars [spoiler]they both have good games, like SW battlefront[/spoiler] hmmm....... As far as we know, forunnners can travel outside the universe, and use weapons that fire light, that can vaporize you, precursors most likely have more damaging weaponry. Star Wars had Jedi, rebellion, empire, countless droids, and much more........ I'm gonna say halo
