Yeah, for me I think it was my A500. I have a hard time choosing between that and my spectrum, but the Amiga for me perfectly bridged that gap between 'very little is possible' and 'everything is possible'. Seeing and interacting with primitive 3D shapes was for me as a teenager more magical than the near photo-realism of today's games, even if I'm just as impressed or more so with today's games. It's the same principle, I imagine, as loving Star Wars so much because I was a child when I experienced it for the first time. I wonder if I would love them as much if I watched them now as an adult. Watching the prequels is a good indicator...
