Tekken 6 is seemingly shaking up the core mechanics to bring some newcomers into the mix.
The core focus would be how the new mechanics work when trying to enhance what was already palatable. It does translate to the game pretty well. Tekken 6 adopts its already refined style with excessive combat threaded with passionate cinematics. Naturally, how the game plays is the most significant aspect of a fighter. Details of the playable fighter are enhanced with a sense of photorealism and don a vibrant color palette - making them very accessible even for less adept players. Tekken 6 already looks the part - the visuals in character models, over-the-top combat animations, and level environments are stunning. That puts extra pressure on developers to deliver a refined Tekken experience with each release.
There are communities around the games that place them into high-regards as one of the most competitive fighters out there - organizing tournaments, competitions, and achievements around them. While the Tekken franchise doesn't have the stature of Street Fighter and Mortal Kombat - its fanbase is dedicated.
