Yeah I used to sell at flea markets alot with my Dad, not video games but odds and ends so I would come across alot of video games and music. This was years ago when his health was better and I got tons of stuff that I was into for really cheap, mostly rock records and video games. I only bought records that I was going to listen too but with video games I would buy up mostly anything of value without any intent on selling. As I got older and with emulating I don't really see a need for all the old games and hardware, it's fine if you like to collect I have nothing against that. You could say the same thing about me collecting old music, why collect old records when you can just have everything digital, which I do but I enjoy having the records too and the album art.
Recently though I don't know if it's just a lack of interest or what but I've been thinking about downsizing all of my collections. I took a bunch of stuff I got for nearly nothing to a local video games show and made decent money but I still have alot. I guess I've come to the realization after my brother passed and I basically inherited all of his stuff that I should sell what I'm not really playing/listening to and just focus on what I really want to keep forever. Of course not forever but you know what I mean, what I'm going to use for the rest of my life. I have totes and totes of video games and consoles and records since I never sold anything since the 80's but trying to find buyers who aren't scumbags and get a decent price is kinda tricky. I'd much rather it go to someone who enjoys the stuff as I did than someone just trying to make max profit.
I got all my NES stuff together and not counting my childhood NES and a few games that have sentimental value I'm trying to come up with a price. I have 3 consoles, one is boxed and over 100 games, tons of controllers that I picked up over the years. I want to be fair but don't want to give it away.
