The original Patrick's Challenge was an unfinished Commodore 64 computer game. It was the predecessor of the text based adventure game The Steven Miller Quest.
In June of 1996, Patrick's Challenge for Windows '95 was released. It bore no resemblance to the original Commodore game.
Patrick's Challenge II is similar to the first Patrick's Challenge windows game. For Patrick's Challenge II, Reldni has made a few enhancements including the ability to build your own games.
