GameMaker is an easy to use card based development system which allows you to create simple adventure games with graphics, buttons, and text.

There is no programming required, but it does have a small programming language which can be used to make better games. Just draw the pictures, type some text, click a few buttons, choose some options.

. . and PRESTO, an adventure game is completed! You can then compile your game into a real stand-alone application that can be uploaded to online services.
