Though the different story modes aren't very deep or long-lasting, they are perfect for the handheld platform. Each character has a background storyboard cinematic that plays before their individual story mode, and after a few matches with familiar opponents, the story mode will culminate in a boss battle and a closing storyboard cinematic. Since this mode was not ideal for the handheld platform, the focused story mode was swapped out for character-specific mini-story modes. However, this mode was heavily cinematic and featured long melee-style levels. Tekken 6's main feature was its robust story mode, which incorporated new characters Lars Alexandersson and Alisa Bosconovitch.
By preserving as many elements from the console title as possible, and replacing anything that couldn't be duplicated with alternate content, Tekken 6 on the PSP is definitely a title that portable fans would be remiss to classify as "just another port." However, Tekken 6 on the PSP is one title that comes very close to measuring up to the high bar set by the console version. Whether it is graphics, gameplay, modes, or a combination of all three, ports almost never live up to the potential of the original console game.
Generally speaking, when a console game is ported to a portable console, quite a bit is lost in translation.
