I like the concept of an interactive documentary, but it is as interactive as searching through a folder on my PC. Some of the documents seem redundant, because of their later contextualization in video form. The biggest pro is giving us playable versions of prototypes and different ports - something more games should do! Nevertheless, some things should be an e-mail - this should have been a linear documentary. These were the parts I enjoyed the most. (And the games of course. Played more Deathbounce and Karateka than I imagined beforehand!)
