Game Maker 7.0

Game Maker allows you to make exciting computer games without the need to write a single line of code. Using easy-to-learn, drag-and-drop actions, you can make professional-looking games in no time. Games can have backgrounds, animated graphics, music, and sound effects, and once you get more experienced there's a built-in programming language that gives you full flexibility.

What's best, Game Maker can be used completely free of charge, and you can use the games you produce any way you like. You even can sell them.
