Wait all companions can never be killed not just Dogmeat?

In all fairness, New Vegas did this first.

It was optional. Todd doesn't mention an option here, and also expresses a design philosphy that heavily implies this extends to quest-giver NPCs. He's saying "if the player might re-load for this situation, then we shall prevent it entirely." A huge chunk of the playerbase reloads if a quest NPC dies, so...

Has Todd lost the plot? "'Okay, the dog can't die, because you're just going to re-load.'"

Edit.. Jeez why didn't they just include the option "Watch a bot play the game for you"?

This should be optional like it was in New Vegas.

While I would be inclined to agree the majority of the population reloads, I also find it odd that the man who likes to get up on stage, hype people to Oblivion and back and mask "streamlining" with phrases like "enabling player freedom"....and here he is discouraging the freedom and the desired playstyle of those that don't reload. Like why not make this optional? It worked in New Vegas. Just give it a toggle option. Cause as it stands, that's not enabling player freedom for those that don't reload.

And hey, it even has some words in the OP!
