I'm not sure how popular Act of War was, I never hear anyone talk about it though, but it was a C&C like RTS from 2005, complete with live-action cutscenes. Good game, had a good expansion pack without the live-action, and it had a spiritual sequel called Act of Aggression that was complete garbage.
