Xerte is a free, open source toolkit for creating quizzes, presentations and other learning applications. It was developed by the University of Nottingham. While Xerte's primary purpose is to make educational media, it's capable of making games (e.g. using Flash) as well. Xerte has many features to make applications accessible to people with disabilities. There's a choice of color schemes that provide good contrast between text and background colors and have been tested against many types of color blindness. It's easy to make applications controllable with the keyboard rather than the mouse, as well as to enable text-to-speech output.
