Was it just me, or did the audio level increase a few times during the video?
Anyways, I would say the best video game series for a movie would be Star Wars.
To actually respond, I'm not sure any of the games I normally play would directly translate into being a good movie.
Like a Bethesda RPG, a la Fallout or Elder Scrolls, has a lot of lore they could use to make a great movie, but I feel like directly basing it off a specific game would miss out on a lot of the fine details. I almost feel like there's almost too much lore and stuff to make into a movie or movie series.
A movie placed in the Fallout universe would be dope though.
Any of the shoot-em-up games probably wouldn't translate well either because I don't think a video dedicated to hyperviolence would go over well outside of a rather niche market. A Just Cause 2/3 movie would probably be pretty boring since it would literally just be an hour and a half of explosions and a guy in a squirrel suit.
GTA V might be able to work, would depend on how it's planned out. Would probably have to cut a bunch of stuff out to minimize the setting switching so much since it could get confusing, but the general plotline would make for a fun watch.
Ooh, something based on the original Mass Effect series would probably make for a good TV series. Kinda in the vein of Star Trek/Stargate/Firefly being all space-y and stuff, but different.
Ooh, ooh, or Red Faction. Disregarding the pile of shit that was Armageddon, the Red Faction series would make for a great Sci-Fi series of movies. Evil corporation, worker uprising, low-key hero being a badass, action scenes. Really hits all the necessary cliches right there.
