Sega Model 2

If Sega's Model 1 proved that real-time 3D belonged in the arcade, the Model 2 made it gorgeous. Arriving in 1993 from Sega's AM2 division and built with technology partners including GE Aerospace and Martin Marietta, its defining trick was texture mapping: instead of flat Gouraud-shaded polygons, surfaces could now wear photographic skins. Suddenly a racetrack had asphalt and advertising hoardings, a fighter had cloth and skin, and the arcade looked years ahead of anything in the living room.

The launch of Daytona USA in 1993 became a cultural touchstone, its eight-car link cabinets, sing-along soundtrack, and rolling-start spectacle turning arcades into social arenas. Virtua Fighter 2 followed and stunned players with the speed and fidelity of its texture-mapped combatants, becoming a genuine phenomenon in Japan. Sega Rally Championship introduced surface-dependent handling that racing fans still revere, while Virtua Cop and The House of the Dead defined the modern light-gun shooter and Dead or Alive launched a fighting franchise from the same silicon.

As a piece of hardware the Model 2 had real personality: fast, bright, and confident, with a knack for smooth motion and vivid color that made its games feel like theme-park rides. It was expensive and heavy, but operators embraced it because the games were destination pieces that pulled crowds.

Commercially it was one of the most successful arcade platforms of the 1990s, anchoring Sega's dominance of the coin-op world during the genre's last great boom. Its games were ported and re-ported for years, and its aesthetic, all shiny textures and exuberant motion, came to define the look of mid-decade arcades. The Model 2's legacy is that transitional moment when 3D stopped being a novelty and became the medium's mainstream language, with Sega leading the parade.
