This is an absolutely amazing documentary that discusses how the whole personal computer industry started, leading up to the Commodore 64 (the best computer of the 80s and the best for gaming). It was a kickstarter project (

It was previewed at the World of Commodore conference in Mississauga this weekend (

BTW - the World of Commodore conference was amazing - some really good speakers, including Bil Herd (the creator of the Commodore 128). I grew up with a Commodore 128, and it was the best computer Commodore made in my opinion
