You can already murder, kill, and obliterate anyone you want, must you destroy their homes too?
Except Children. Unkillable, everyone turns on you if you attack them, they hover in areas as watch dogs mainly. The break every-single-rule of NPCs in the rest of the entire game. Every last one!
Seriously, Bethesda, PLEASE: Either switch back to Fallout 1 and 2's method of handling children (the same as every other NPC, except people disilke it more when you attack them. OR Remove the ability of children to detect sneaking and report crimes -- This could even be handwved as having advlts not believing the children. OR: Simply dont' put any children in the game. It creates a mobile zone of rapidly changing physicals. This means we lose the ability to suspend disbelief. They just are completely above any and all rules that could benefit the PC, and of infinite, unfair amounts of NPC benefit.
Make the game's harder not by adding unfair omniscient god children who summon the entire town from inside a hut, not by ratching up to -6x/+6x damage done/damage taken.
The children are by far, the WORST idea. No exceptions. Do NOT put them in a freeform game unless you intended make it "A freeform game except for all those points where we wanted to shoehorn you in to very specific courses of actions by creating God-Sentries." That is not a fun game. It wasnt fun in fallout 3, and it wont be fun in Skyrim. Its just another huge disconnect betewen your character and the world.
You can cleanse the world of evil dragons, saving the cosmos for all time by your heavy victory. And now you cant defeat a child in armed combat. I hate to say this, but its really stupid. leave children out. Its super easy; just change the shoehorn, oneway quests that involve kids into non-annoying formats that have more than one path because its not against an Extra-Infinity.
