Before I get into my opinion on the documentary, lets address the elephant in the room.

I find it incredibly silly that people give this a negative review simply because its over 200GB in size, even going so far to state that they couldnt play the game because it took too much space or too long to download.
When in reality they couldnt figure out how to disable the DLC from being downloaded,

Even if you have the DLC enabled upon downloading the game, Steam will download the game before anything else.
There is nothing stopping anyone from playing the game other then their own stupidity.

Now, onto the documentary.
Upon deciding to download this Free content, it will be installed into the Psychonauts 2 directory.
Its 203GB in size, 33 parts, 24 hours and 54 seconds long, with individual run times ranging from roughly 20 minutes to 1 hour and 50 minutes.

It offers an exceptional look into the history of Double Fine, the unique developmental environment of the studio, the human aspect of it and the many constraints that come with the development of a video game over the span of seven years.

It portraits all sides of development, from creative brainstorming, to writing, to concept art, the first steps of figuring out what they were trying to make, programming, funding and more.
The struggles and joys of staff, whether its the head of the studio, the producers, the individual production leads, level designers, artists, programmers, sound designers etc.

At the end of the day every person working on this project is human after all and trying to find a work/life balance while creating a video game isnt an easy process whatsoever.

It displays that creative ideas can spring up in places and moments you might not have expected.
That giving those ideas the freedom to take root is something that should be encouraged and fostered.
But also that some things are just beyond the control of any individual with events like Covid, California wildfires as well as technical issues springing up out of nowhere.

Yet all of those experiences combined led to the creation of Psychonauts 2 and this documentary is an incredible view behind the scenes of that process.
