When I joined TSR in 2009, I actually registered under a random name. Back then I really liked the name Killian, which is actually a french male name. Don't ask me why, I modified it a bit and made it mine.
I left my sims game for a few years, and when I came back I decided to create. I had the choice of keeping my old account or create a new one, but I chose to stick with Kilhian. But it was still just a name, until I read in a decorating tutorial a tip about making a sim with your creator name. You pick up rocks, insects and what not to further personalize houses before sharing them.
I had made a few houses for the Sims 1 and thought it was some nice thing to do, so Kilhian was born as a sim. She started on her own and without cheat on October 2011 as I was just starting playing the Sims 3. I only had the base game, so she had to do with a small EA starter house in Sunset Valley for a while.
Back then I took those screenshots for my boyfriend. We are now living together, but I am glad I got all those, they are still very good memories. The quality of screenshots improves along the way :)
