paladin181: It says in the requirements "Controller/joystick" It doesn't say recommended. I'm honestly not seeing what's confusing.
You're right. I was first tricked by the "Mouse, Keyboard, Controller/Joystick" requirement. It gave me the impression that the game could either be played with a joystick or keyboard and mouse.
And now that I remember, I owned "Star Wars: X-Wing" and "Star Wars: TIE Fighter", two DOS games playable with keyboard and mouse. I've never had "X-Wing vs Tie Fighter"... Sorry for the misleading information!
This [url=http://en.wikipedia.org/wiki/Star_Wars:_X-Wing_vs._TIE_Fighter]Wikipedia article[/url] confirms that the game is only playable with a joystick.
