The game that put the PlayStation on the map for fighting games.

Plot
So the backstory is, Heihachi Michima throws his kid (Kazuya) off a volcano as a test to see his sons strength as a test to see if he is a worthy successor for the Mishima Ziabatsu corporation. Kazaya (who is 5 years old at the time) nearly dies but makes a deal with the devil. He swears revenge on Hitachi for throwing him off the volcano and enters the iron fist tournament. Clearly this family feud was beyond Jerry Springer…
There also a bunch of other fighters who enter the tournament for money or to prove themselves, including a robot and a bear.


Gameplay
Each character corresponds to the face buttons on the PlayStation controller, with two buttons being assigned to the left/right hands of the playable character, with the X and O buttons for the left/right which can be used to issue kicks to the opponent. Guarding is done by holding the left, or right depending on where your character is facing the opponent. Some moves cannot be guarded against.


During the first 9 seconds of the fight, you can press the select button to switch between different views (1P Start on the Arcade version)
Arcade mode consists of nine stages, for the first seven stages these are opponents picked at random, on the eighth round you will fight against a rival, depending on the character chosen. The 9th round puts you against Heihachi, and after winning the match the end credits will play. The arcade version runs through a montage of KO replays for each round, whereas the home version will show the characters ending FMV.
Tekken featured different fighting game stages that are based on different real world locations, and each location has their own background theme.

All characters have an alternative costume that can be selected by pressing Triangle/Square, instead of X or O. There is also Devil, who is Kazuya but serves as the final boss of the game. He can be unlocked and become playable character by completing the Galaga mini-game at the start with a perfect score.
There is also an unused charicter that exists, known as Wildcard. Believed to be Kazuya’s long lost twin, he grew up and was raised by Yoshimitsu who adopted him into the Manji clan where he learnt how to fight. He entered the iron fist tournament to reunite with his family, but after learning of the devil gene and Kazuya’s heart of darkness, Wildcard left and was never to be seen again.
Versions
Arcade: The arcade version runs on the PlayStation based Namco System 11 board, which is very similar but with a different sound processor, the Namco C76 and C352 which was also used on their System 22 arcade board. This version only allows a limited amount of characters to be selected and playable compared to the home PlayStation release.


PlayStation: Released 1 year after the launch of the PlayStation, this version included FMV based endings for each of the character which explains the back story. Like other Tekken games, the home version has a revised soundtrack, but has the option for the arcade original soundtrack also.
The home release of Tekken 5 features an arcade version of the first Tekken game, which looks and play exactly like the actual arcade release, no improved textures or effects. I’m not sure if these are ports for the PS2 hardware or if they’re tapping into the PS2 PlayStation backwards compatibility.


Other Differences
The only other noticeable difference is the question mark animation spins on the arcades character select screen, whilst it is static on the home release. An animation also plays when a character is selected on the arcade, but does not display on the PlayStation.
On the stadium stage, a screen can be seen in the background that shows a copy of both characters fighting, the arcade has a static texture in place of this. The stage name is also different, referred to as Marine Stadium in the arcade, and Stadium in the console version.

In Monument Valley, the sun sets in very round for the arcade version, but in the console version the sun sets only one, and stays down for each round
These differences may be due to the arcade version having a larger amount of VRAAM compared to the PlayStation version, 2MB vs 1MB. However the main system RAM remains the same (2MB), along with the main CPU and the GTE (33.8Mhz, although MAME shows this to run at 67Mhz since the PSX CPU divide the incoming clock signal by half, so its still running at 33.8)



Originally Tekken was known as RAVE WAR which appears on a couple of Ridge Racer cars on both the arcade and PlayStation. Also to note the game was originally in development for Namco System 22, which Ridge Racer and Time Crisis had run on.
