mostly because you want to be able to take a break from it once in a while. so if it was applied to powered armor or the stealth suit all you have to do is take the armor off. this will allow users to not uninstall when it gets annoying. also it will take far fewer scripts and it wont require a line for every single action. since you cant make money off the mod in any way that makes it so paying the actor (if he chooses he wants to be paid) then it will come out of your pocket, or not happen. so limiting things is a plus here. that's figuratively impossible. you also have to remember what are the odds you can even get the guy to do it? by only voicing actions it will bring things down to maybe a hundred to five hundred lines of dialog where as for what you want to do you would probably end up with more dialog for the mod then spoken lines in the game its self. So your saying more dialog is a bad thing ? i disagree I also don't see how it would be impossible just. Lots of lines like "character decided to shoot "NPC name" until they died" but player could stop and run away or not do it and over all the narrator could maybe just narrate the mr. House story line of leaving from doc Mitchell and going to the strip and the rest of the game from there but of course keep it interesting with choices and alternative narrative for not taking the choice the narrator wanted not saying get a narration for every time you open pipboy or equip stuff just use named npcs ignore randomly generated nameless ones use certain roads and locations
