Not so much as a game movie per se, but in some older games like Wing Commander IV, the live action videos were great, and added a lot to the game itself. Mark Hamil and Malcom McDowell added a lot of atmosphere to those games. Same with some of the opening cut scenes for the "Janes Combat Simulations" whether it was live acting or animated, it added so much to the story.
Even having real actors doing the voice acting was a nice touch! Don't see a whole lot of that anymore.
Remember this? Mark Hamil on the left, not sure who is in the middle, but that's "Biff" on the right, from Back to the Future,lol
