YoYo Games GameMaker 8: Make Free Games
GameMaker 8 is the latest version of the free easy game development software Game Maker from developers YoYo Games Ltd.

Game Maker enables you to create your own Windows computer games without needing to know how to write any code. Built in drag and drop actions can be used to create simple games in a multitude of genres: platform, role-playing games, arcade games, 3D games and even your own unique ideas.

Once you have become familiar using drag and drop you may want to learn Game Maker's built in scripting language, GML, which enables you to extend the possibilities of your creations.
