Applications of these techniques in video games not in today's market Clashing Fists Used the concept of FSM (slightly altered) to control the computer controlled fighter in the game. Clashing Fists Used the concept of FSM (slightly altered) to control the computer controlled fighter in the game. Spade Used FSM with (slightly altered) to control the multiple opponents to the player

Should computer games be taken seriously? Because of the prevalence of video games within our society they should be. Videogames posses a lot of power in terms of it recognition in society. Developers have to be more responsible for what they put out there for so many to experience.
