Basically kind of similar to a lot of other threads here. Here is -- you guessed it -- a thread to discuss voice-acting in video games. Your favorites, your least favorites, the most bizarre you've ever heard... you get it.
Posting links is definitely encouraged. Explanations are probably a good idea.
Personal favorite in terms of questionable-ness of the voice acting goes to Heavy Rain, which is a French game. It's supposed to take place in America (specifically Philadelphia, if I recall). Characters who are not known to be immigrants have very clearly non-American accents and there aren't even attempts made. Here's an example. It's a great game and all, but it's just... really questionably voiced.
