Otaku no Video

Shows the lifestyle of hikkiomori, otaku and other Japanese recluses and outcasts. 

These two credits played almost the same subject, and the protagonist is similar to the NHK 

You're antisocial and anxious. You are welcome! 

Stories that explain the reality of otaku culture, showing the consequences that brings in the lives of their culture, obviously only speak Japanese but a reflects the protagonist who takes refuge in to leave reality and achieve happiness . 

Both shows represents in an accurate, and painfully relatable the otaku fandom from the period they've been made. NHK feels much more personal and does delve on the mentally unstable psyche on it's cast, while in Otaku no Video we can see the semi-biographic story of the founding of studio Gainax. Both shows feels as a slight critique and serves as a way to expllore the otaku fandom, with both it's obsessiveness and delusions. 

both are centered round otaku culture and showcases both positive and negative concotations with the culture. 

The protagonists of both anime are otakus, both are trying to create an entertainment product to enter the otaku industry. 

Watch Otaku no Video for a shorter, more old-school, non-student-based, less realistic (toward the end) otaku story. Watch Genshiken for a longer, more recent otaku story that is completely based in reality and gets deeper into character developments. 

Two animes that explore the different cultures of the otaku, and how it is seen in society. In both series we have a group of college students that takes up most of their time in playing, watching anime, reading manga, doing cosplay. Both try to parody and at the same time give a space for these people who consume and are consumed by the current society that has formed in Japan comically and almost real. 

Both shows tackle the Otaku scene in a semi-serious and critical but comedic fashion. The MCs get deeper into the world of Otaku while exploring specific niches like model kit building, cosplay, doujinshi and more. 

Both anime show how Otakus life is. 

Both cover anime production, while Otaku no Video covers a moment of anime history! 

Both are (sort of) hommages to the 80s otakus and, while Otaku no Video is a mockumentary about Gainax's roots, the DAICON videos are the roots itself.
