I found this old advertising display in my storage from the time when I actively collected Handhelds. Is there a die Hard #Nintendo3DS Collector who is interested in this? how much could this be worth? Pls RT
Congratulations 🎉 first PSP full set I've ever seen. That's awesome 👍🏼
I finally did it! I finally completed the North American PSP GAME Collection! I share the challenges finding these including HIDDEN GEMS, RARE games and the one PSP title that took me YEARS to FIND!! WATCH ➡️ youtu.be/zWdq9jdrwmQ
Seeing these things make me drool and wanting them even more xD #segamstersystem #mastersystem #retro
It's been a year since Billy has passed away. I still feel heartbroken about this. He's been a huge part in my journey as a video game collector, influenced me in many ways. I muss you dude. @thegamechasers 😥😢
I discovered some old things from my former Handheld collection. Match if the Millennium for the #NeoGeoPocket and a #Wonderswan Carrying Case. A few fragments of my big Handheld collection I had back in 2014. 😅
5/10 SEGA Cards complete!
Bank Panic & Great Soccer join the collection! 🎮
Yes, I bought Great Soccer twice 😅 It’s part of my PAL Full Set AND my SEGA Card Subset, so I needed a second copy!
Halfway there! 🔥

You're quarterly reminder not to use plastic coffins on retrogaming anything These should be strictly for the card and comic collectors. – at Yoe, PA

Honestly that's the game announcement/trailer that made me hyped the most. IDC about GTAVI. All I want is Mighty Cuphead Adventures as a physical copy for my #mastersystem 🤩
Now in development at Studio MDHR, it’s…Mighty Cuphead Adventure! A true 8-bit action platformer compatible with modern consoles, PC, and the Sega Master System home gaming console. Radical!
