In the years since its release, Tekken Tag Tournament 2 has remained a beloved entry in the Tekken series. Its legacy is seen in subsequent titles, such as Tekken 7, which have continued to refine the gameplay and expand upon the series' rich legacy. The lessons learned from managing save data and providing post-launch support have informed how modern games are developed and supported.

The base game requires you to play a lot of matches to earn Fight Money and unlock hidden characters and stages. Many players use downloaded "100%" or completed save data to bypass this grind.
