But I remember a time (Morrowind) when EVERY NPC could be KILLED. I miss those days. Sure it was annoying when you killed one of them by accident but it made the game feel so much more real.
When you did kill a quest essential (Main quest only) NPC you would get this lovely message...
"With this characters death, the thread of prophecy has been severed. Reload a previous save to restore the weave of fate or persist in the doomed world you have created!" or something like that
As I mentioned earlier, this made the game feel a lot more real when you actually had to worry about who you were killing. Also (sadism?) I miss being able to go on a grand killing spree and literally killing every NPC that didn't respawn. Anybody else feel this way?
I can't help but feel like The elder scrolls has had training wheels since oblivion with the invincible NPCs.
