Stuff that, back when you were in the economic clutches of your parents, you could but dream of having.
For me, there were several. The Dreamcast was the first, then the PS2, back in the early 2000s
More recently, I’ve been completely enthralled by the Amiga and what it offered back in the late 80s. That’s a system that was never available around my parts (Brazil), even as a clone product or contraband
I had an Amiga 500. It was great and I felt very fortunate to have one when I was a teenager. At some point, you could either buy the Amiga 500 mini or get a refurbished one. There is a nice community of Amiga enthusiasts who buy and sell hardware and also share software online, along with sharing emulators. This year for my birthday I might buy myself an Amiga 500 mini. I miss my old one, which is long dead and never coming back.
