Meteor, Butterfly and a blade (originally called 流星蝴蝶劍.net, AKA: Meteor Blade, 流星·蝴蝶·劍, Meteor, Butterfly, Sword, Liuxing Hudie Jian) is an action role-playing 3D game adapted from the famous martial arts novel of the same name by Gu Long from China, developed and released by 昱泉國際 (InterServ International) from Taiwan in China in 2002. It is the world's first martial arts-style 3D fighting online battle game.

Tekken (AKA: 鉄拳, Iron Fist) is a very classic 3D fighting game series for both arcade and home game consoles, developed and published by Namco from Japan. Its first work was produced in 1994, appeared only on the arcade console at first, and was later ported to home game consoles. As a hardcore fighting game, Tekken is extremely realistic and exciting no matter in action design or graphics rendering, thus occupying one important seat among all fighting games in the world all the time. As we all know, it even spawned comic books and movies.
