I think first person moving is better than just third person moving / aiming... With MGS2 you could aim in first person, but the transistion between the regular Metal Gear view (third person) to first person was rather confusing with angles in some situations. I think with being able to move in first person, will make it easier to prepare for aiming and shooting, if you know what i mean, and in the jungle i think this will be more important, because you need to be more ready at all times.

If you see in the movie (right at the end, the bumble bee nest), if you was just waking through the jungle, if you was not going in first person, you would not notice that automatically (maybe only when its too late), so some situations it will be very important to use, and extremely helpful!
