Would Argonians get more stat penalties in the cold than other races?
Don't get an Aneurysm, you won't be forced to use Fast Travel. Though, I think I would have to use it a lot to prevent my 'walking tank' character, Ruprecht, from gaining too much Athletics and Acrobatics skill to prevent him from running too fast and jumping too high and far.
guards need to be fixed
if you can kill all the guards in the vicinity, the bounty should go away.
if you run away, when you come back, there should be less guards and wanted posters.
and like AC, tearing them off reduces your notoriety.
