Storyline does not change gameplay.
Weapon variety may change gameplay somewhat, but the core remains the same. Weapons that 'look cool/different/don't exist' don't change much. They just make it less obvious what real-life weapon they're trying to imitate.

Even a small change in gameplay can ENORMOUSLY increase how fun one game is compared to another. Furthermore, fun storyline is just as important as fun gameplay to an overall fun gaming experience; both have to be present and balanced properly for the game as a whole to be fun or "worth the price of admission".
That said, I have no idea how Halo holds up to my standards, I just wanted to put my point out there.

Story is the reason we play games?
show me proof of that please. I say we play games because, *gasp*, IT'S AS SIMPLE AS WANTING TO PLAY GAMES.
Your proof, sir:
Granted, I disagree how it's THE reason we play games, but I will argue that it is
A MAJOR reason we play games.
