Inclusive design is a design process (not restricted to interfaces or technologies) in which a mainstream product, service or environment is designed to be usable by as many people as reasonably possible, without the need for specialised adaptions.

Inclusive design looks for solutions that fit everyone. For example, instead of a building entrance with narrow stairs and a narrow wheelchair ramp, the entire entrance may be a slope that is attractive, barrier-free and minimalistic.

Simplest accommodations to consider in game design:

Inclusive game design makes sure that all players feel welcomed to play and engage with the product. If the game is not accessible, whether that be physically or mentally, or if the player is not represented then they may feel isolated and miss out on opportunities to learn, collaborate or just have some fun.

Guidelines to inclusive and accessible design

Game accessibility guidelines | A straightforward reference for inclusive game design

Game Accessibility Guidelines is a collaborative website built by a "group of studios, specialists and academics, to produce a straightforward developer friendly reference for ways to avoid unnecessarily excluding players, and ensure that games are just as fun for as wide a range of people as possible."

It provides detailed examples of how we can ensure that our games use inclusive and accessible design features, splitting the methods into categories (motor, cognitive, vision, hearing, speech and general) so they are easier to understand.
