You looking to protect yourself, or deal some damage?
Do you get to the Skial district very often?
For me, it's a hard tie between Oblivion and FO New Vegas.
I was never a real big gun game person when it came to SP games. I like to play with magic, swords, shields, etc. The fantasy of it all captured me, this love only grew being able to end the siege of a castle I would own, getting to plan an assassination all under the ruse of a party-where all the guests are just victims to take out one by one, where overconfident thieves really cannot comprehend that the fire spell crafting master that just speared a poor wolf into the afterlife might be dangerous
On the other, you can kill everyone and not break the game. (or you can you know, play it any other way and have rich encounters where your charisma choices actually do matter with a lot of variation, and finally a lack of illusion of choice. you want it dead?
you can kill it. nothing is stopping you.
