I am just chiming in with the crowd that thinks these are all ugly.
Sure, i see where they are coming from. And, from an execution stand point, I think they are very well executed. I also think the amount of glow is just right. I just do not like the way they look. Every one of them looks... blunt, dull, not sharp. Also, they all look heavy, unbalanced, unwieldy, and just all around unusable.
I realize that Could's blade in FF7 was over sized as well. Then again, silk button down shirts were in style during that time. And MC Hammer pants were just heading out of style. Times change, and so do consumer tastes. Everyone linking up weapons from the past is not considering this. At one point in time, huge, gawdy[sp], weapons were actually in style. The "in" thing right now is to design weapons with flare, but yet still seem like they would function well (unless the overall design of the game is over the top fantasy). By every measure, these designs just fail that test.
Side Rant:
And for goodness sake, i wish they would give the curved blades a rest. There are so many other types of blades out there to choose from as a reference. Despite better stats, I didnt even attempt to go for the Aeolian Scimitar. While this is a design that was actually used as a blade at one point in time. I believe it is one of the ugliest.
I can only guess that this is because I only see sword motions which swing instead of stab. So, that limits the blade choices to use as a reference. For example, using a slashing motion with a rapier just looks goofy. For the FFXI guys, compare the Ridil attack animations to the Joyeuse. They are the same, but the joyeuse is a rapier (a stabbing weapon by design). A rapier just doesnt look natural with a slashing attack motion. Is it too much work to add attack motions based on weapons? I dunno, but Demon Souls and Dark Souls does it.
