Background info
I post on YouTube so I want an exciting character. I've done Mage and Stealth
What's the hardest thing I could do?
Unarmed on Master seems appealing
hardest or tedious? the game isn't all that hard, especially once you figure out crowd control in the game. a more stealthier option would provide a least a more premeditated, calculated approach. personally, i split the difference between two combat specialties (one-handed and archery), so starting out i had no, one strong combat specialty, though my sneak increased the effectiveness of practically all my attacks--which were typically first-strike, no reply.
also, i might suggest not investing in any crafting skills (i.e. smithing, enchanting, alchemy). this forces you to play the loot rather than build your own, but more importantly it staves off the temptations of taking advantage of the crafting options in the game.
