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
That, and I miss the Dream Machine. It was fun.
