That's why I'm thankful that this is an action-oriented game with a smidgen of RPG elements inside. Otherwise I would be a little more cautious about who I plant my axe into.
Actually, in a proper rpg, there`s no reason why you can`t do all the bad things you want to do like real life- If you`re really smart, like Garrison64 in his example.
The problem is in games like Skyrim, there`s no real cost for what you do, you can run around and kill and you`ll get a bit of a bounty, maybe. Neither should anyone, no matter how powerful he is, be able to kill entire cities or half of one without getting a bucketful of
woe down on him. And I mean woe that gets heard about elsewhere.
Even if he escapes, every other city around abouts should soon hear of him and close their doors to him whenever he approaches. See how long the Player lasts with no shop to buy from and no Inns to rest at. He`d be reloading and playing good boy pretty fast.
Do it right and you`ll still get by, but you won`t be doing any massacres of innocent people unless you have a death wish- Like reality.
