Jabarkan Reception dari Tekken 6

Critical response to Tekken 6 among reviewers has been generally favorable, with the PS3 version scoring a 79 on Metacritic and the 360 an 80. IGN praised the additions to the game's mechanics and modes, as well as the large cast, which they felt should appeal to most gamers. GameSpot agreed, liking the new additions to the roster, most notably Zafina for her look and moveset. They noted that Tekken fans would enjoy the new mechanics as these meant practicing more combo styles, such as juggle combos. On the other hand, Eurogamer was more negative, stating that by the time the game was released there were other more appealing fighting games. At the same time, they conceded that it was far more popular than those in the East. They found the graphics superior to the recent fighter Soulcalibur IV but not as good as those of Virtua Fighter 5. Nevertheless, Eurogamer felt the returning characters' combos felt familiar, and long-time players would enjoy playing them. VideoGamer.com made a similar comparison noting that while other fighting games might entertain gamers more, Tekken 6 was faithful to the series' roots. This included its use of intense motion which the reviewer found easy to learn, though they had mixed opinions about the new mechanics that had to be learned.

The PlayStation 3 version of the game garnered some criticism for its excessive load times when run without installing it previously, and its initially laggy online multiplayer component, which was later improved via updates. At first 1UP.com was negative towards the game's poor online mode, but once Namco patched it the score was revised upward.

The game's Scenario Campaign mode was subject to mixed criticism as well. IGN regarded it as a disappointment, citing bland environments and repetitive enemies. VideoGamer.com also criticized the mode, saying it was not fun, and the plot involving the Mishima family was not enjoyable. GameSpy praised the game for its variety of traits taken from different types of games. GameSpot gave the plot-oriented Scenario Campaign mode far more positive comments, as well as the amount of replay value provided by the possibility of playing other characters besides Lars. Game Revolution also had mixed opinions. They noted the camera had some issues that might affect the moves' input—moves like Kazuya Mishima's Spinning Demon—which could easily still be performed to take down enemies without difficulties. The reviewer compared the style of the Campaign to role-playing games, referring to the way the player can power up the characters.

The PSP version received positive reviews, with Metacritic giving it 82 out of 100. IGN said the portable version had greatly improved loading times compared to its console counterparts. GameZone regarded it as the "definitive version of the game", despite lacking the Scenario Campaign and the graphics of the main console; the port still managed to retain good graphics, the console's d-pad was felt to be far more useful than the one in the Xbox 360 controller. GameSpot and Eurogamer also shared similar opinions on how the PSP port managed to impress, retaining the large cast, and for its responsive controls.

During its first week, the PlayStation 3 version of Tekken 6 sold 103,000 units in Japan. According to Media Create, this made it the fastest-selling fighter. It remained so until August 2012 when the PS3 port of Persona 4 Arena broke the record  with sales of 180,000 units. In May 2011, Namco Bandai reported it had become its best-selling game from 2010 with 1.5 million units sold. The game got to number three on the UK sales charts. In North America, the game sold over one million units as of August 2010. Upon its release in Japan, the PSP port sold 25,131 units. As of May 2011, Tekken 6 has sold more than 3.5 million copies worldwide.

In 2009, Tekken 6 was nominated for a Spike Fighting Game of the Year award but lost to Street Fighter IV. However, it still won the Best PSP Fighting Game and Best PSP Fighting Game Readers' Choice from IGN.
