Wouldn't it be great if you could shape your weapons into whatever form you can imagine? Select a base weapon (ie. silver mace, ebony shortsword, etc) from the interface similar to how you select the race/six of your character. From there you could change a blade's width, thickness, shape, point, etc. just like how you change the shape of your character's face. You could select decals and engravings to place on an axe's edge or a hammer's head in a manner similar to how some games allow for face tattoos. This whole process could be kicked off by sacrificing a weapon to a forge (either through an NPC or as a feature in a player's house), and that weapon's statistics would determine the damage, weight, etc. of the final created weapon. I'm sure a use could also be found for items like gems and gold/silver nuggets.
I imagine creating armor with a system like this would be complicated, but weapons would probably require less effort to implement than the current system for character creation. I feel that this would be a worthwhile addition to the Elder Scrolls series because immersing yourself in your character aesthetically is almost entirely dependent upon what items you have equipped. It just always seemed wrong that Brim, my holy crusader, should be carrying an evil-looking, lava-encrusted, Daedric longsword just because it has the highest stats.
I hope you, Bethesda, consider a mechanic like this for the next Elder Scrolls game. As for Elder Scrolls fans, what do you guys think of this idea?
