When was the first time you got interested in Garry's mod?

Back on 2010 when i was 12 years old, i saw a video of a guy building a rollescoaster in sandbox, it was a dream come true having a game that i could build things easily without coding, nowdays i have 3k hours played and its still one of my favorite games i've ever played... What about you?

I once was on youtube, when i was also 12, i was browsing the front page of youtube, and i found the gmod idiot box. i started watching it and couldn't stop laughing, so i bought the game and to this day, with over 2000 hours, i don't regret it.
