I own a nodachi that's as tall as I am. I also own a Heron Marked blade from the Wheel of Time book series. Then I have a cool Chinese one that's hanging on a plaque on my wall. Can't say which of the three is my favorite though.
I'll have to second Siaynoq when he mentioned the Great Sword, Dark Storm. That thing kicked ass. Also, my car's name is the Green Destiny, it has the blood of thousands upon it's windshield....
And I still remember when you can finally use that Reaver of the Great Orc. Could that have been the only really big sword that you liked?
Hehe, yeah. It was so big, you could only really see the hilt of it in your inventory. And you needed those Gauntlets of Might just to hold it. But it killed Ruloi in one hit. After that part of the game, I pretty much ditch the sword. But I do so reluctantly.
I liked narsil or sting....from lord of the rings, but again, like most people, i just like swords so it really doesnt matter to. The only swords I absolutely hate are the anime ones that are bigger than the characters.
