I mean, I'm half the age of any Merlin in existence but I grew up with a fascination with the history of electronic entertainment, mainly with a focus on videogames. It was like a dedicated-purpose oversized calculator with like 5 or so built-in games, like most of the time, except it was portablized by its terrible display. The concept itself was further improved upon later by a similar, yet interchangeable, system, then by Nintendo's Game & Watch series, &.....well you should know the rest by now. It exists as one of those critical points in history, fucking fascinating at the time though looking back today only has a tiny fraction of the appeal even by its successors like a year or two later.
