How does having the game third person perspective affect the gameplay?
Free of the first person view you can do a ton of things with the game and character that you couldnt do otherwise. When Marcus communicates with headquarters his finger goes up to his ear, his head lowers, and you see him chatting. If a grenade goes off nearby he cringes; when he slams into cover you see him grimace. In first person all of this is lost and all you see is this gun in front of you.
