Best Voice Acting of 2012

When used properly, and with proper talent, voice acting can enhance a gaming experience beyond what we expect, beyond what can be programmed alone. Sure if it is done poorly it can make a serious section of a game pure comedy, but that is not what we are worried about here. The nominees for best voice acting of 2012 are:

Guild Wars 2
Borderlands 2
Halo 4
Mass Effect 3

And the winner is Borderlands 2. With the voices of Dameon Clarke (Handsome Jack) and David Eddings (Claptrap) they give great dialog and make the game very entertaining. Serious moments are taken as serious as needed and comedy is pulled off without a hitch.
