I gazed around at the horizon, which was just a jagged green vector line, denoting mountainous terrain. Here on the surface, Archaide looked exactly like the environment of the 1981 game Battlezone, another vector-graphic classic from Atari. In the distance, a triangular volcano spewed green pixels of lava. You could run toward that volcano for days and never reach it. It always remained at the horizon. Just like in an old videogame, the scenery never changed on Archaide, even if you circumnavigated the globe.
