just think about this would the time it takes to craft something shorten as you get better and the quality increase...therefore in reality someone who has made 1000 swords could do it faster and better then a person who has just started their first. Also most smiths work with an apprentice....or several to do a task i think some artists...lworking on large projects had dozens of other people helping thm...so in reality yea it may take a single(or even 2 people) to make a single sword in 3 months but we could just increase the laborers an viola a dozen workers could do it in a week lol. So reality all the limitations in a game cannont simulate reality...also by the way i could use modern techniques and make a higher quality sword then they could back then because they way to define steel is by its purity....most smiths could only make pig iron sword...a true steel sword would be a rare case because of the processes they used.
