Shumi that's an impressive collection you've built up in the time you've been a member here - I remember way back when you got started, now the shelves are struggling with the weight!
Thank you. The boxed Famicom stuff goes back one row behind the stuff in front. The loose stuff, two rows. The shelves are struggling, but that's more a critique on the poor quality of the shelves than on the quantity of games.
Around the time that I joined, I working in Akihabara. The job was incredibly stressful, and I'd hit the shops nearly every day after work to take my mind off the day. The bulk of my FC collection came from that time. After a day where I wanted to jump out the highest window, I'd "splurge" (but always within my hobby budget) on this or that.
A year later, I worked in Yokohama, at a job that wasn't so soul-crushing, but WAS near two pretty great second-hand stores. Most of the non-FC stuff came from that magical time.
I've finally settled at a job that's nowhere near any used game stores of any note, so any future collection enhancements won't come so frequently.
