3D engines are everywhere these days — you can probably name at least two off the top of your head — but in the late 1980s, they were a new and exciting phenomenon.
One of the first companies to figure out a means of making a reusable 3D engine that could be applied to multiple games without too much difficulty was Incentive Software from Reading in the UK, who developed a system they dubbed “Freescape”.
The first game released that made use of Freescape was named Driller, and unfortunately at the time of writing I’m yet to play it. This was subsequently followed up in 1988 by Dark Side, which I did play, however, and have some rather fond memories of.
