Playing stealth can get boring. For example, after you've realized you can exploit the AI to loot every friendly guard NPC by doing a stealth chokehold, then equipping their armor and unequipping it and slowly dragging it to the only haggler NPC in the castle and selling every piece of armor for a bunch of gold, waiting 24hrs and repeating with all the armor you've dropped on the ground, then once you've lockpicked the entire castle town and assassinated half the villagers, your first approach to every problem is to pickpocket everybody of everything and then snipe them from afar, except you quickly obtained a maximum-rated suit of full-plate armor and a repertoire of every weapon of every highest grade... bleh. Now tree-climbing and tree-branch-jumping, that would be really fun skill to have!
