When you've tried every possible game and still don't find one that really makes your skin crawl, maybe it's time to start creating your own video games!
With Adventure Game Studio you can create your very own games from scratch, including every single element: rooms, characters, objects, dialogs and more. Though limited in genre (it only enables you to create point-and-click adventure games), the program includes highly detailed configuration menus and editors with which to create your personal adventure.
That said, don't think it's just a question of selecting a few basic graphics, writing some dialog lines and done. Creating games is an extremely hard task that involves writing a clear plot, having some skill in drawing characters and understanding how source code and scripts work.
Adventure Game includes both the game editor and a game engine, along with a debugger and compiler with which you'll be the first one to test your newly created adventure. Also, a complete Help section and a thorough tutorial will help you during your first steps in videogame creation.
Adventure Game Studio does help you create videogames, but you still need to have some background knowledge – or at least to be ready to acquire it.
