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
A friend of mine had the Turbo Grfx-16 and I was extremely envious. At the time it was probably the only one in our tiny town and I would go over to his house and play it. Years later he was extremely jealous when I snatched up a New Geo Pocket. Everyone was playing Gameboy but NeoGeo Pocket had some amazing games but no marketing. Luckily I managed to snag a bunch of game sfor cheap at a used game store so I ended up playing it well into 2010 when it was finally destroyed by accident.
