So you start your quest armed with a stick with 5 attack power.. its a decent stick being swung like a sword. Down the road you upgrade for an actual sword with 10 attack power.. what you could do with two stick wacks now only takes one sword wack. Already this seems odd. Is this a very crumby sword or was it a fantastic stick? Moving on you upgrade again for a new sword with 20 attack power... was your old sword dull and this new sword sharper? Skip to endgame and upgrade to megasword with 200 attack power. How/why is this weapon so much more damaging? Elvish metals? Dark forces? Magic? What are the alternatives to nonsense unsustainable upgrading?
