For those interested in the development of the game Super Meat boy, the documentary _Indie Game_ follows the two developers during the making of the game, as well as the makers of Fez.
Second that. The greatest thing about that movie is that it doesn't glorify being an indie game developer at all. Watching that movie is one of the main reasons I've held back from just giving up my FTE position and going off on my own. I feel like I'm just not young enough anymore, and you really have to have a certain kind of support from those around you.
It also shows how obsession plays a huge role in the potential for success. Not all who are obsessed are successful, but it is a large factor. That's not to say that obsession is good. Unfortunately, it often places emphasis on something that really does not matter in the end. But, for the few that have a crazy idea and try to bring it to fruition, hopefully it is something they look back on later in life as a good thing, whether it was a mistake and they learned from it, or whether they grew as a person because of it.
If people could obsess about doing something that helped others, that would be much better, but not everyone has that tendency, and maybe super meat boy really had a positive effect on a lot of people making the world a better place- I don't know.
I'll back up that endorsement. I've seen it 3 times now, the last time being last night. As an aspiring game dev, it is really motivating and enlightening.

I thought it was a good film.
