First of all, I want to point out I could not find the proper title for a mod such as this. So yah.
Anyway, I think it would be cool if there was a mod that added items such as shortswords, broadswords, shields, staffs, tomes, etc, with each type of weapon totally effect the way gameplay works. Kind of like Kid Icarus Uprising. But not only would it add items, but sometimes, maybe like a finishing move, it would play in a quicktime event with cutscene jumps and all that fun crap. I just think a mod should add these things. That would be awesome.
