Richard Waugh - Albert Wesker (the real voice, not the new RE5 garbage with DC douglas.)

Alyson Court - Claire Redfield.

Patric Zimmerman - Revolver Ocelot

Tony Jay Elder God.

Sally Cahill - Ada Wong

Steve Ritchie - Shao Kahn

I know there are 3 RE actors in there, but I can't help it. Great voices, other than Steve Burnside.

Keith David.(AKA Goliath, Spawn, The Arbiter, Captain Anderson)

There are three voices in this world that I would give my right arm to have and his is most defiantly one of them.

Honourable mentions
Tony Jay (surprised no one has mentioned Megabyte)

Michael Ironside(I wouldn't really call him a voice actor, he just has one of those voices like Tony Jay and Keith David that is so unique and can never be replicated)

Jennifer Hale(The most fitting voice for Sonya Blade ever)

Mark Hamill(Do I really have to explain this one?)
