Video games seem to believe that all swords are alike, and you can fight the same way with each one.  They also believe that there is an ultimate sword, and all others are weak...

Obviously, that is false.  Any sword can be useful if you use it right, and a sword used must have a style of fighting as well. 

A good example of a game that doesn't believe this is Kingdom Hearts.  The different keychains of the Keyblade have different attributes, but sometimes the worst can be the best.  The Ultima Weapon is not the best, but is useful if you are a magic user.  The Sweet Memories Keyblade is awesome if you are looking for items.  Even the first Keyblade is useful if you suck at defense. 

Blades are powerful.  Yet even the best can be beaten.

Half the battle is luck.
