Call of Duty: Ghosts uses the exact same scene from Modern Warfare 2
If you loved Call of Duty: Modern Warfare 2, I have some good news for you: you're going to love Call of Duty: Ghosts. The two games are so alike that Ghosts features the exact same cut-scene from Modern Warfare 2, just re-skinned.
NeoGAF user ThaneKrios posted a video from YouTube that shows the ending of Modern Warfare 2 re-purposed in Ghosts. My guess is that through some sort of Inception, Leonardo DiCaprio, Ellen Page and Joseph Gordon-Levitt built elaborate dream mazes and went three dreams deep into Infinity Ward's subconscious to plant the idea of using the exact same scene from Modern Warfare 2.
Or it was to save money and time. Yea. Probably the second one.
