The Tekken games have always been the most popular fighters for the ps1. Tekken1 was very blocky, bad character details, and did not move very smoothly. However it still had fun game play, and unlike the other tekkens it offered great challenges, and moves that were always fun to learn. Then, Tekken2 came out, and was a vast improvement over the first. It had more moves and combo systems, better graphics, and new characters. Then Tekken3, the best tekken and the best fighter for the ps1. It features many new characters, lots of moves and combo systems. Good, smooth graphics, and nice looking FMV sequences. New modes such as tekken force (a very fun side scrolling game, similar to the old nes game, double dragon). A very addictive and fun minigame called tekken ball mode (play it with some friends, it's a blast). Also, all the normal modes such as survival, arcade, and time trial are all there. As for the difficulty of the game, it of course features three modes, easy, normal, and hard. I was though, very surprised with the challenge of arcade mode. But the boss, ogre was way to easy, and even his second form was easier than his first! My favorite characters are yoshimistu (sp?), Jin Kuzama, and Bryan Fury. As for the replay value... it kept me playing it for a week or two and that's pretty good. I have not yet played TTT (Tekken Tag Tournament) but I will soon. Plus I am very excited about Tekken 4. So if you want a hardcore, action packed fighting game that is very realistic (they even considered gravity so they jump the normal height) then I highly suggest this game to you. It's the best!
