I can't say for sure, but I don't think The Dark Eye expects your character to be involved in the creation of your weapon from mine to scabbard, but it does give you a rules system that allows you to interact with it at any stage. The world of the Dark Eye is much more interested in the economics, so you'd never get a blanket statement 1 gp = a peasant's yearly income, like you might find in D&D.
D&D used to have durability rules, but they so rarely came into play that it might as well not have.
The idea of anyone running out of arrows in BG:2 is baffling to me, maybe +2 arrows, but not arrows
I'm not going to die on the hill verisimilitude vs. convenience, but I still appreciate that things like gold have weight, even if the amount of space 1000+ gold coins might take up isn't an issue.
