I began at the young age of 8 in 2002.  I was too young to attend the events for Masks, scythe etc however.   I have been on and off since then, with probably 10+ accounts made.

My favorite memory had to be when I completed Monkey Madness and obtained my D Scimmy.  It took me forever as I had no idea guides existed back then!

i started rs quite late around late 2009 i believe but havent stopped playing since

I was probably about 10 years old shortly after RSC launched. (2001/2002ish)

Off and on since then.

2006 at the age of 9, got introduced too it by my best mates older brother, about 20 of us used to play it together, unfortunately im the last survivor!

2005. I remember being stuck in the Maze Random Event for hours lol... 

I started in Octoberish of 2005! My play time is a little higher than yours though (embarrassing). Going on a year lol.

I started in 2004-2005, I remember watching a late night gaming program on ITV and a segment of it mentioned Runescape, at that time the questing, etc looked amazing - I initially got me and my mate David into playing it. I remember the nights me and him speaking about what we’d be doing that night like making steel armour or doing sheep shearer, the good old days lol.
