Consumer electronics: Video games: The next wave: Interactive video-disk technology lends reality to arcade games, but purists believe the ultimate lies in real-time computer-generated graphics

Two new developments in arcade video games show promise of rousing the industry from a torpor that has gripped it for the last year. The first development is the third generation of real-time raster-based and vector-based games, offering three-dimensional solid graphics for the first time. The second is laser-disk-based games, which, while failing to give players real-time control and the freedom to move at will in the game, overwhelm them with graphics heretofore achieved only on movie screens.
