Or at least the return of crossbows, whatever happend to crossbows?
and @ Komodo, no because even a woman's high heel shoe can be used to murder someone. Just because something is Fancy doesn't mean it's useless.
Now, try to actually FIGHT in high heels, in a real fight you have IMPULSIVE moves to do, and you have to maintain a good grounding, otherwise you weapon won't have any impact, and you'll not be able to withstand an attack as good as you could with a good grounding (which quite frankly, is IMPOSSIBLE in heels, minus very small ones). This might seem great for fencing, where the point is simply to touch your enemy, but in a FIGHT, you want IMPACT, and you want to KILL your enemy, not simply make a cut on his belly
Seriously you can kill people with a cabbage and you can actually kill someone in real life with a shoe, why can't you kill them with an elaborate weapon?
Again, you can kill people with anything, yes, but actually FIGHTING with it is something else. Killing with cabbages and other things that don't look like weapons, is good for assassins who don't want to be predicted, but in a fight with someone who is armed right, you will NOT have a chance of using it. It would be like trying to throw a tennis ball at someone who has a gun.
As for the weapons, well, let's just say a good weapon needs to be hard enough not to bend, but "flexible" enough not to shatter on impact. Add to that the fact that it needs a good balance to be used effectively, that it needs to be heavy enough to actually have an impact and not be recoiled, yet be light enough so that your "recovery time" after an attack (and before it) is minimal. So basically, while a few fancy designs could be do-able, having some gold-plate on the blade would only make the blade heavier, thus, making the balance shift too far away from the handle. The result would be that the blade would feel much heavier, thus, if you miss once, you're open for WAY too long. And not only that, but the fancy design on the blade wouldn't last long either. Adding things like crystals in the pommel or the handle would not only make the balance shift too much towards to handle, thus making the blade too easy to puch back, but it would ba rather useless as the precious stones would break after one or two hits (those materials are hard, they resist to friction, but they're not sturdy, and break from the slightest of impacts)
A few engraving on the blade wouldn't change much though, and actually, it has been done a few time already (especially in eastern asain countries such as China and Japan). It wasn't seen that much throughout Europe though, as in Europe, There was no finesse involved in the fights. Their swords weren't even sharp. You swinged it with as much strenght as you could, and it would usually break bones more than it would cut
And to finish it all, there are actually enough fancy weapons in Skyrim. Just look at Daedric, Ebony, Elven, Glass...
