Why did you have to call out the Halo haters by saying something positive about Halo...?
Halo is different from Star Wars, but in terms of popularity, I'm far from counting it out. Halo is damned popular, for better or worse, but the only thing keeping it from reaching this mythic "classic" point is people who arbitrarily can't accept the possibility that Halo was good. Maybe they didn't like it, but that didn't make it trash.
I had a film professor who would rant and rave anytime someone called Star Wars a "classic" and took up entire class periods with well-intentioned, intellectual proofs of why Star Wars was not a classic. And yet, it IS a classic, none the less. Popularity isn't something that needs to be proven. It's one of the few things that just is. Halo doesn't need to meet a set of obviously stacked criteria to be great.
Now, it is NOT the "next Star Wars". But it will be a classic of games the same way Star Wars is a classic of film. They were both mass market, high impact media and were wildly successful. You can't deny that. They are classics that serve as a landmarks in their respective genre and media.
For the majority of these comments, please... please stop stacking the criteria so you can fulfill your irrational beef with Microsoft. Halo was a great series for it's target audience, and Microsoft-hating recipients of botched lobotomies aren't in their target audience.
