A high-quality port of the Namco arcade game "Ridge Racer" contributed to the PlayStation's early success, and garnered favorable media in comparison to the Saturn version of Sega's "Daytona USA", which was considered inferior to its arcade counterpart. Namco, a longtime arcade competitor with Sega, also unveiled the Namco System 11 arcade board, based on raw PlayStation hardware. Although the System 11 was technically inferior to Sega's Model 2 arcade board, its lower price made it attractive to smaller arcades. Following a 1994 acquisition of Sega developers, Namco released "Tekken" for the System 11 and PlayStation. Directed by former "Virtua Fighter" designer Seiichi Ishii, "Tekken" was intended to be fundamentally similar, with the addition of detailed textures and twice the frame rate. "Tekken" surpassed "Virtua Fighter" in popularity due to its superior graphics and nearly arcade-perfect console port, becoming the first million-selling PlayStation game.
