Treyarch wants the singleplayer story to be longer lasting experience than the campaigns of the other CoD games.
Mark Lamia, the boss of Treyarch, wants the singleplayer story to have a higher replayability than the previous entries in the series. He also admitted that Call of Duty games have had short solo campaigns. That's why he wants his team to focus on the replayability in Black Ops 2. Therefore the developers added branching storylines and new paths.
“There is something that multiplayer has, but the campaign hasn’t had so much of: replayability. If you look at the Strikeforce levels, and you look at us going after choice and sandbox gameplay, what it does is put replayability inside the campaign.”
“Look at the branching storylines: all these things, I believe, will drive people who enjoy the campaign experience to go back and play it again, because you’re going to have some new paths that you didn’t experience, or even in the case of Strikeforce levels, levels that you didn’t even play: it’s possible that you might not play all the Strikeforce levels on your first play-through. And then there are the story-endings.”
“I think the goal at the highest level from a design perspective was accessibility plus depth of gameplay plus replayability. To me, for a campaign, that’s the Holy Trinity.”
