Our Amiga 500 was second hand, and some of our games were hand me downs, so at one point we had the manual for Frontier but not the game. And that manual was just absolutely fascinating, this whole imaginary SF world you could blast around and go on adventures in. I was a big SF/space nut and the most sophisticated game I’d played was Lemmings. It seemed completely impossible.
So when the game itself did eventually show up and it really was this vast sci fi space to explore how I wanted, it absolutely blew me away. It was like actual virtual reality (and looked like it, with that slow frame rate and those flat polygons). That was the first game that really became an all-consuming fixation.
