I happen to be playing Castlevania: Aria of Sorrow right now.
I can't immediately choose the worst overall right now, but I really for the life of me can't understand why it will wait until most of the way through the game to give you the option to switch out your uber-powered sword/whip/etc. with...
...punches. No, I'm not kidding. They do roughly one-third the damage and have the worst range in the series, and yet somehow they thought that just by having them be fast, the weapon would be worth its value somehow.
Yeah, you can keep your fists to yourself, I think I'll go kick ass with my giant Golden Sword over here.
