The Futurama video game was not very good, but it was distinguished by terrifically written cut scenes. At a certain point, I gave up the game and found a cheat code that allowed me to just watch the cutscenes sequentially, and I always thought they should be released as an episode.
They were, but the resulting episode is hit and miss. They have taken all the cutscenes, and since many cutscenes are intros to gameplay, they show little bits of the gameplay to give you a sense of what's going on (although for some reason there are several instances where they show the end of a boss battle but not the beginning, making it feel non-sequitorish).
Written by and voiced by the same people who made the series, there are some very funny bits in The Lost Adventure, and a wonderfully clever ending. But because so much of the episode is devoted to setting up gameplay, the story comes across as episodic and underdeveloped. There's about the same amount of material as you would find in a regular episode, but to fully flesh out the story for the game you would need the story sequences to be twice as long.
Still, watching the game this way is a lot more fun than trying to play the game!
