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 remember seeing Stunt Car Racer and Shadow of the Beast running on an Amiga for the first time, and being absolutely blown away. They were so far above anything my trusty Speccy could do, it was almost funny.
Of course, both these games would eventually come to the Spectrum (with varying degrees of success) but to say that it wasn’t really the same would be a grotesque understatement.
