Oh absolutely!
I started collecting in 2008, but my video game collectorism really took off in 2010. I had just freshly graduated college, my girlfriend, now wife, and I had just moved into our first place together, and I had recently started my first real job, which didn't pay a ton, but enough to fuel my collecting hobby, at least at the time. I lived for the hunt and would visit thrift stores daily, religiously refresh Craigslist for deals, and on the weekends, I was a regular at my local flea market. There were also a ton of indie video game stores and second hand media stores (ie. Gohastings, Entertainmart, 2nd and Charles) within a 40 mile radius of me. At least for the first few years I was collecting, very few other people were doing it which meant tons of deals. The deals were really the best part; I'd go to the flea market with $60 and come home with 30+ games and consoles, none of which I'd even consider filler.
On top of all that, the youtube gaming scene was really starting to take off around the time I heavily got into collecting, so I was constantly learning about all sorts of games for older consoles I'd never even heard of or completely overlooked when I was younger. It was just an fun, interesting, and productive time to be a game collector and I threw myself into it all 110% at the time and loved ever minute of it.
I feel like the writing on the wall about these good times coming to an end began to show its ugly head around 2013 for me. Nearly every place I used to go hunting for games had become less and less lucrative. Beyond just way more collectors and resellers visiting these same places for games being a factor in this, many of these places, especially thrift stores and second hand media shops began to get "collector employees" who seemingly worked at these businesses just to snipe the video games as soon as they were brought in. The worst place I used to hunt for games that fell victim to this was a media store called Tradesmart. By about 2015, it seemed like half the employees that worked there were either collectors, resellers, or a combo of both. I had to get very aggressive and clever to even stand a chance of getting any desireable games from that store, which of course made me the target of ire from most of the staff that worked there. I'd later find out from a former employee of that store, that it wasn't just me, but the employees were literally fighting amongst themselves over games that were brought in on trade. But yeah, it was around 2015/2016 especially that I realized collecting games, and more specifically hunting for deals on them, had become noticeably less fun for me, but it was still my primary hobby.
I feel like my collecting era officially died in 2017 thanks to me being forced to sell off a decent chunk of my collection to fund what insurance wouldn't pay for back to back medical emergencies. I didn't immediately go, "welp, I'm not a game collector anymore! That's that!" but rather it was the gradual realization that by that point I'd acquired 90% of all the games I'd ever wanted and also that my games were far less important to me than I'd originally thought. Having to sell so many of them, especially some real heavy hitters was the catalyst for me realizing this. Still, I fought against my diminishing interest in collecting by trying to collect more for systems I'd previously only collected casually for, or trying to collect boxes and manuals for loose cart based games I owned. Still, every time I'd acquire some new US Saturn game or a new box for an N64 game I owned, I noticed myself experiencing less and less joy as a result.
I feel like the moment I had where I realized I was more or less done collecting games, especially retro games, was shortly after I moved in 2022 and met up with a local collector who was selling off a bunch of his games to make way for his first child which was on its way. I bought a ton of Genesis and Saturn games off him for around two grand. As I was on my way home from doing this, I realized I felt practically nothing for the huge score I'd just acquired. I got home, put the games on my shelf, and went about my business as usual, just $2000 poorer.
At least by the strictest sense of what a collector is, I guess I still am technically a collector, but I certainly don't maintain a massive list of games I'm after like I used to. I buy almost no retro games now thanks to flash carts and ODEs satisfying me there, as well as all the retro games I still have. I still buy and add a ton of modern games to my collection, but only stuff that I have immediate plans to play. And unlike in the past, if I play a game and don't like it, or realize maybe I'm less interested in the game than I originally thought, I have zero reservations about selling it. As I said earlier, I'm far less attached to my games than I once was, which overall I feel like is a good thing.
But yeah, sorry for the massive tangent there.
tl,dr: I have a ton of nostalgia for my collecting era between 2008 and 2022, and especially between 2010 and 2014. Those were such fun, special years for me. I acquired literally thousands of games during that 4 year period, most of which I bought for a bargain. Deals were everywhere, some of the best places I've ever looked for video games were still around, and I also met a ton of great collectors too during this time. Also, the online zeitgeist around gaming felt so alive and vibrant around this time. Hell, it's during this time I joined VGcollect and my most wonderful memories of using this site were during the first 5 or so years I was here. I do miss that time and even though most of the places I used to buy games at are gone, the world has changed heavily since then, and so have I, I still remember that era maybe just as fondly as I do being a young kid and experiencing some of those older games for the very first time when they were brand new.
