How much time will it take me to watch the .hack series? I'd like to give .hack a go, however I have very limited time in my schedule so I often avoid picking series with too many episodes.

I would like to know :


How much time does it take to watch everything ?
How much time does it take to watch main part of the series?
To watch everything including ova's, movies and the likes would take you 2091 minutes (34.85 hours) spread over 83 epsiodes. This would cover:


.hack roots
.hack//Sign
.hack//Gift
.hack//Unison
.hack//Tasogare no Udewa Densetsu
.hack//Quantum
.hack//Liminality
.hack//G.U. Returner
.hack//G.U. Trilogy
.hack//Intermezzo
.hack//G.U. Trilogy: Parody Mode
.hack//The Movie: Sekai no Mukou ni
.hack//Versus: The Thanatos Report
.hack//Tasogare no Udewa Densetsu: Offline de Aimashou
.hack//Quantum: Sore ike! Bokura no Chimuchimu-chan!!


And if we take a look at How to start the .hack series and its viewing order? we can determine that the only true cannon series are:


.hack//SIGN
.hack//Liminality
.hack//Roots


Which is only 1380 minutes (23 hours) spread over 56 episodes
