If you count time spent in AG actively looking for games as well as spectating and funners not just Leagues, and time on Worms Armageddon related forums, websites and chat servers, christ, I would literally have many many years worth of hours combined...
Gaming in general, i'm 35, been gaming actively since I was about 5 which started on the Spectrum ZX which I was on for a few hours every day, I got my own game boy in 1991, my uncle had the NES which we played all day every Sunday when we went to visit our gran, and we also got a mega drive, master system, SNES, playstation, saturn, dreamcast, n64, ps2 throughout the years which we played in all the spare time we had, I also had a PSP, has a shitty Atari for a few weeks lol. I also remember playing this game on the BBC computers at school that involved decision making, there was a witch, and a red apple... There was also this F**KING AMAZING treasure island pirate game but can't remember if it was on BBC or Spectrum ZX and for the life of me cannot remember what it was called, but it's one of my earliest memories in life.
About 14 which is when I discovered PCs and Worms Armageddon in 1999. I was gaming for at least 8 hours a day pretty much every day I could for the next 18-19 years, i'd even put a duvet over my computer at night to block the sound of the 56k dialup so I could stay up at night for another 2-3 hours playing warmers with people like TheFudo, marco, thewalrus etc.
When I had a job, i'd play from when I got home to when I went to bed, for years when working nightshift i'd only sleep for 5-6 hours to get more time to BnG.
Then there were the years and days when i'd play all day every day, often for 2-3 days at a time without sleep playing WA.
There were a couple phases where I didn't play as much when I had a girlfriend but still managed put in a lot of hours.
I've only had one long break from playing the game from Feb 2019 until Sep 2020 and even then I was still watching games on a shitty laptop but probably only about a couple hours hours in that time
In the 21 years i've known this game, including the big break I had recently, i'd say at least 1/5 of that entire time was associated with WA.
