what i wreckon a game needs is heaps of different selections of weapons!
swords, axes, daggers, knifes, short swords, long swords, hammers, double axes, two handed swords, bows, longbows, shortbows, crossbows, wands, staffs, pole axes, spears, harpoons, ninja stars, spikes gloves, claws, darts, throwing axes and heaps more, u get the point im trying to say!
each weapon should have different powers
and there should be heaps of different types of those weapons. This is so no1 gets bored of the same old weapon and that they can always try different ones.

on a game called diablo the weapons have sockets that u can insert gems or runes into them wich make them have different powers like \'giving the player extra stats and skill levels and adding power to there attack, making them faster,  
and having advantiges on enemies, and lots more!:)
that would make every weapon be different.
And for those smithers that dont agree, i think that the higher smithing level the higher of a chance to change the weapons powers, and a chance of making the weapon with a socket:P
that always makes a game fun!
