It would certainly take a LONG time considering there are, what, 1000+ releases and many of them containing multiple maps. Some maps take five minutes to play, others up to 30 or sometimes even 60+ minutes. So playing every single map is quite an undertaking to say the least.
I’m playing all maps with an editor’s rating of 4/5 or higher or a user rating of 3.3/5 or higher in chronological order. I started about a year ago, and I’m about two thirds of the way in. I’ve played around 500 releases in total. It’s been a blast so far, and quality gets better and better.
What they didn’t mention was they were doing it instead of working or going outside, so I’m sure they’re probably stuck in some horrific neurotic prison like in Requiem for a Dream. Nobody said Quake would be easy.
I have passed all the maps in the http://www.quaddicted.com/ Some of them for many times. First dowload for the lust time I passed through the collection was downloaded at 5 march 2016. It was the day I formated c: and started download and play the maps again.
There is one only map I couldnt pass! It is too dificult for me, it is

It is perfect work. I love this map in 1997, and I love it now! I know one russian champion Mpa3b, who passed it for me and made demo. But even he didnt do it without saving and loading as one peace of cake.
Prior to 2010 I attempted to play all released maps for Heretic and Hexen including !HZone. It took me 2 to 3 years to play them all and I didn’t play them everyday. After I stumbled upon Magic and Mayhem for Heretic I gave up. I assume Quake has just as much maps as that. I assume it could take about 2 to 4 years to play them all. By the way, if you start playing all the Doom maps today, and play them normally, it would take you more than 30 years to finish. Quake has a lot of maps, but it doesn’t have that many.
Progress report: Finished maps from July 2017, about to start August 2017. Switched to playing all maps (instead of only those with good ratings) when playing maps from 2016, since there aren’t really many bad maps released recently.
EDIT: Hmm, it seems I’ve actually played all maps from 2014 onwards. Apparently I picked up all the ones I had left out from the previous couple of years when I made the switch to playing everything at the 2016-year mark. I plan to reach further back to unearth more esoteric stuff once I run out of newer maps. Wonder when that will be…
