I've never thought about it, but Forrest Gump really works as a video game. You have your running levels, your war levels, your ping pong levels, your socially awkward levels, your fishing levels and your save-Jenny levels. You can even have a pick-a-chocolate level.
It's a movie that can easily be turned into a video game. CineFix animated what the game would look like in 8-bit and yeah, I'd totally play it.
