Don't forget hunting! I spent two whole hours just roaming the forest that is north-west of the Imperial City and killing deer with my bow. It was so fun. I wandered to find two of them, then shot one. The other ran away, so I quickly took my venison and chased it for about 200 yards. I started sneaking, then came around a stump to find it looking into my face. Then I shot it before it ran out of sight.
It is also fun to find one, then hit them when they just start to fade from view due to distance. Like, they are grazing, then you back up enough just to see a faint outline, then shoot. VERY entertaining.
I think what makes it so fun is the gratification of the bowshot and marksmanship.
