Littaly's one word sentiment is really all you need.
It doesn't even need the exclamation mark and all caps. I mean, come on. This is a silly question. You may like Halo a whole bunch but how can anyone even venture to compare Star Wars to Halo. Let's look at the comparative scale, there's Lord of The Rings, Star Trek, and Star Wars. There is nothing else up there. The next level would likely be the Mario level, Samus and Sonic are up there. But Master Chief... I think you can put him on the next lowest tier with Solid Snake and Final Fantasy.
And that's not a burn, that is still really really good. It's better than Half Life. The problem comes from trying to compare Halo to something that is clearly levels above it.
Look, Green Arrow is an excellent super hero, he fights for the little guy, his story lines are always full of drama and real human emotion. And he's even had a couple of Justice League cartoons focus exclusively on him. But can you honestly compare him to Batman? To explain the metaphor for the less sophisticated forum goers, Halo = Green Arrow.
I will say this, going against the flow of a lot of the people on this thread: There is nothing inherently unoriginal or average about the subject material of Halo, So Aliens have taken over the earth, many excellent sci-fi stories are premised on that exact theme. Star Wars action is set around an oppressive conquering force rudely taking control and ruling, difference being it is more than one planet. Where Halo does not compare to Star Wars is in the art and passion with which it was assembled; the ground breaking nature of the work; and the universal nature and themes of the story, based on the structure of the epic tale.
And a good 80-90% of the Star Wars games and Star Wars / Halo novels are derivative, unimaginative, and just plain lousy (three different ways of saying the same thing I know, but well earned in this case, someone smack Lucasarts and Bunjie for letting their IPs suffer these corporate shenanigans).
