On Oblivion

I've played Oblivion on 2 separate occassions both ending rather quickly. For 2 reasons. For the fact I cannot move when over encumbered, arrows weight 0.1 pounds... And because of its convoluted map system, I had a very hard time finding my wat around. Something also bothered was the Charm the Shopkeeper minigame, I just wanted to sell my loot!
