Complex adaptations, usually only used when aiming for specific niche audiences. Considerations that are only applicable to certain game mechanics, require more budget, specialist knowledge / advice to implement, or don’t benefit as wide a range of people. However they have incredibly high value for the people who do benefit from them.

- Provide very simple control schemes that are compatible with assistive technology devices, such as switch or eye tracking
