^ Yeah, because they used a lot of smoke and mirrors a.k.a scripting, effects and cinematics. You were always shoehorned through alleyways while the rest of the war seemed to be going on around you.

Gameplay was sacrificed for the sake of the story. This trend has been more and more evident with each game released. SP is synonimous with interactive-movie these days.
