I don't mean in terms of story and plot, but in terms of actual game mechanics. Look at the old Rainbow Six games against the new ones, same for Ghost Recon. Hidden and Dangerous was a great game too. Those games are actually hard, and have gameplay that isn't just "watch explosions, shoot some enemies, get shot, sit behind wall to recover HP". Just look at Rainbow Six 3 against Rainbow Six: Vegas 2, the second one was about as linear as you could make a game, the first one gave you a lot of options in how you would achieve a mission.
