There's a guy known as Ulillillia who has a somewhat similar long term obsessive project (a game, Platform Masters). There was a documentary shot about him that unfortunately seemed to go off the rails in post-production and wasn't released.
Probably not quite what you're looking for (I'd like to know more about the documentary, too), but here's a 1h49m Youtube video of the author giving an overview of Platform Masters: https://www.youtube.com/watch?v=rzjW0xsW7_A
