The fighting game genre started out as a solely 2D venture before the medium was capable of anything else. Following the release of Sega's Virtua Fighter in 1993, developers and fans alike started to see what fighting games could do in the 3D realm. Tekken essentially took that rough template that Virtua Fighter had presented and injected more personality, style and characterization into it. Tekken soon began to distinguish itself as a premiere 3D-fighter that was a massive hit at the arcade. Tekken began to prove that 2D wasn't the only way of doing things, particularly as sequels were released and the graphics gradually became smoother and less blocky. Another big difference in Tekken as a fighting game is move execution. Other fighting games rely on fast and accurate button inputs to execute moves, while Tekken's intuitive system saw a button linked to each limb, meaning it was possible to see and replicate the move without the need for command lists.
