Megaman X4. What are they fighting foooooooar!?
rofl Oh man, I don't know how many times I've said that exact line. Bascially
one of my friends ever knows what I'm talking about, so most are confused. My favorite is Dr. Light's Emler Fudd voice in Mega Man 8.
But, for some seriously bad voice acting, look no further than
Castle Shikigami 2. The site has some great examples, and some of my favorites as well (though not all). It's worth fighting through this whole hard-as-hell game JUST to hear the voice acting. Good god is it hilarious. I don't know how all this crap got past anyone; if I was voice acting for this, I would have just given the script back. I don't think it's even fully the actor's fault, I mean...just listen to what they have to work with! How would you handle that horrific, bloody mass of mangled english?
When you're done, check out the main site for a list of arguably bad voice acting. Much of it is no question, but some isn't as bad as they make it out to be.
