Lesser known videogames made into movies?

[SukkaChump]

I was just curious on which not so well known games would actually make decent movies, not blockbusters i mind you, but something you would go see.
Me personally would have to go with The Dig.

The Dig was based on a small group of astronauts on their way to drill into a large asteroid which is about to hit earth, but once inside this large asteroid they find that it isnt an asteroid at all, but a large transportation vehicle, this ship brings them to a far off planet.

and at this point i'm a bit foggy on the details, but they get there, the crew gets split up and one or two die, the captain is left there with a few crew mates, acts of betrayal and odd alien life forms start to show, not large hulking beasts but small odd animal types..
From that i would need to check up ont he game, but i would like to hear about any not so well known game you think would make an alright movie.
A small synopsis/summary of the game would help out too, not just a list of names
