I think it would be a great idea for Warhorse to implement a system into the weapon crafting that allows you to customise your weapon as you make it. So for example:
You are making a one-handed sword, so you have the option of different pommel styles, maybe different colours for the grip (eg black/brown leather or coloured rope etc) different hand-guards and blade shapes.
Although the game itself wasn’t brilliant, this was one of my favourite things about Fable III. I loved that the weapons were customisable, but it annoyed me that it was down to random luck at doing certain tasks that caused the weapons to turn out differently as a pose to player preference.
Maybe to make it even more unique, the swords could carry emblems or inscriptions, but personally I’m not as bothered about that. I just think adding this feature into the game would make it much more immersive and believable that the character was a skilled blacksmith.
