1: the camera should become "unlockable" when the game is paused in VATS mode. Meaning it should be able to brought into third person mode and be able to free roam. This would allow the player to get a better sense of the battlefield and whats going around both him and his target. for example using grenades, nukes and such would be less risking know exactly where everything is in relation to him and any companions. Unlocked camera would also be needed for the following ideas i have about vats.
2: Movement inside the vats system. Enemies can run while vats is engaged and so should the player. Imagine be able to choose to run to cover, or fire and take cover while in the vats system. the potential for great slow-mo events would greatly expanded. With the camera unlocked from above the player would be able to choose to use AP points to move anywhere he had the range to do so. An auto DODGE skill would be great to add here too. It would come into play automatically whenever VATS movement was engaged. Movement withing VATS would also be a great way to close range on a gun toting enemy to get into hand to hand range. This would help overcome a glowing weakness in fallout 3 melee wpns. You get creamed attempting to close on the enemy.
3: VATS commands for companions. Ever have your companions get there butts killed when they are way way way out of position? Well if VATS mode allowed you to give them commands you could order them to get the hell out of the way, or retreat if they were wounded before they get whacked. Of course vats movement would have to be in effect like i discusses above as well as unlocked camera so you could pick a location for them to scamper off to. It would at the least mean you coudl finally overcome the sometimes spotting companion AI get them to some kind of cover before they start blazing away with their guns.
4: Order of attack in VATS. All these changes in VATS should now require a better working of how and when someone gets to perform an operation in VATS. IF companions are included in VATS then it would have to be made clear who got to do what first. This would also have to be extended out to the enemies. They shouldnt be so entirely hamstrung in VATS like they are at present. They should be allowed to attack back while in the player is in VATS and make it HURT!!! As a side note, the programmers should allow the game to reevaluate the AI's attack while the game is paused. Its seems to me this would make the game more balanced and harder. By having enemies specifically able to react to what your doing in VATS they should be able to perform better and more realistically. This i think would help balance the benefits the player gets inside VATS.
Obviously this would significantly change how the game would be played. i thought about how some people suggested that VATS should be able to continous, as in "turns". But in the end i dont think that would be a good idea. I think the game would be more fun keeping the real time combat in it. I dont think these changes would really effect the people the never use VATS but would definitely make the game more robust for those that do. So let the discussion begin and i hope the people working on future fallout games read this.
