We all ready have guns. They're called staffs. Deal with it.
I just home there's one staff maker out there figures out holding the barrel of a staff at eye level is more accurate at long ranges than just firing from the hip.
I am excited that we have one handed staves. I'm going to use Drain Health in one and Soul Trap in the other. All I need is a large collection of Soul Gems and I'm dual wielding TES guns with unlimited ammo lol.
I watched that whole thing

And no... just no...
Guns have no purpose in Tamriel. Why shoot with a gun when you can blast them away with a shot of lightning?
I did too. Wow that is kind of sad.
Edit: @bigmac2134: No, Peter Molyneux ruined Fable. But then again he gave the ok on guns so you are still technically correct. He also made armor useless, ruined the story, made magic simplistic and stupid, and broke everything else.
