SkyRoads was an old DOS game from the early 90s, although I still played it when I got my Pentium 200 Pro with wait for it...32 megs of RAM.

Anyhow, essentially you had a sort of spaceship that would move forward on straight roads in space, so hence the name SkyRoads. The roads would only go straight since the game was vertical scrolling and you had an ability to jump by pressing the spacebar. The game was addictive because you had to jump over gaps in the road and had all sorts of road surfaces, some that would make you jump higher; some make you slow down, and others speed up. It was also very colorful. Overall it made a good activity while installing linux on another box.
