While I don't find it as charming as Tekken 2 nor do I think it has as good of an atmosphere, Tekken 3 is easily the best Tekken on PS1, still feels great to play, attacks have a satisfying weight to them and have some real oomph when they connect and it just feels way more responsive than the previous games.
I miss this era of fighting games when you had a bunch of bonus modes and unlockable characters, helped to keep people like me invested and actually put in the effort to play the game as everyone.
