I liked Halo and the mulitplayer was always great with friends, but the story never grabbed me until 4. You could tell Halo was in the right hands when 343i took over, at least if we're talking about the story side of things. Unlike Bungie they brought the lore from the books to the games and actually gave the characters some depth and emotion. We also had a tangible villain in the Didact. Can't wait to see what Halo 5 brings in terms of story.
