I think you guys are vastly over estimating the level of costumization that will be in the game, what the hell is a level 3 bronze sword? A sword is a sword, you got the short version the romans used to great effect in their shield lines because they stab well, you got the long version thats better for a general melee without well organized lines and a two handed version thats great for offense but piss poor for defending.
To me, improving a sword is purely based on the material, you can make a bronze sword which is great for stabbing unarmored targets but if they start wearing chainmail you're pretty boned because bronze is fairly soft. Upgrade to iron and you now have decent penetration but high grade steel is still better because it breaks less, thats how you upgraded stuff in medieval times.
Um, no. That is completely and utterly wrong. You don't just take a hunk of rock that has some copper and tin in it, wave your hands at it and it becomes a bronze sword. Likewise, you don't take a hunk of iron ore, wave your hands at it and it becomes an iron sword. First, you have to process your ore to get the metals you want - different methods of processing your ore will result in different levels of purity. To make things more complex, having trace amounts of certain impurities is often desirable. The time progression goes something like this:
- terrible at processing ore, results in poor quality metals
- mediocre at processing ore, mediocre metals
- good at processing ore, good quality metals
- very experienced with what processing methods result in stronger or more durable metals (even if you don't understand the science behind it - which is that trace impurities can result in a much stronger chemical structure)
So basically, the processing of your ore alone makes a huge difference. Then, there's how you actually go about forging your equipment. There are so many ways of going about making an actual sword (or anything else, really) once you have your processed ore. There are innumerable permutations one could make of folding, beating, heating, cooling.... The order, frequency, duration and method of each of the above can all make a tremendous difference.
So no. A bronze sword is not just like any other bronze sword, even of the same size and shape. There can be many difference between identically sized and shaped bronze swords and iron swords besides the materials used. Do you really think a bronze sword made 4000 years ago would be of even remotely the same quality of a bronze sword made using modern tools and techniques? If your answer is yes, then I am amazed and give up. If your answer is no, then you understand why your previous post is wrong.
Now, as a concluding note I'm not saying that this should necessarily be accounted for in the game. My personal preference would be that we are able to improve on our weaponry and equipment in general besides upgrading to 'better' materials, but that's not the point I'm making here.
