A key factor to immersion would be a button to toggle on and of a walking animation. I intend to play this game with a small group of people that intend to play through the game gradually so we can keep the nostalgic 'first-play' feel intact. I was thinking there should be a walking feature implemented, where you press a button like alt or something and your character would slow to a walking pace. The reason this would be immerse is a group of friends are walking through a dark cave and the point man's got his sword and flashlight out ready to fend off enemies while the one in the rear shines his flashlight back to make sure no monsters come around from behind while the rest of the group is in the middle. The mood to this scenario is set by being able to move at a walking pace. It's hard to have an experience like that when everybody's running around and jumping like jack rabbits while the objects on the screen are moving by them at the speed of sound. I consider this a necessity because it's a change that a lot of people would like, it's not that hard to implement and it's completely voluntary; If someone doesn't want to use the function, they don't even have to have that key bound.
