The IGDA's Game Accessibility Committee special interest group (GA-SIG) has posted a survey to catalog games according to their accessibility to those with physical disabilities. The survey is designed to track games that are being developed for players with problems hearing, seeing, and other handicaps, and find out who is developing these games. The results of the survey will be published on the IGDA website and will serve as a reference for future discussions and work in the field.
The GA-SIG was created to encourage developers to make their games more accessible to disabled users and to create a community where information and accessibility methods could be debated and shared.
