Quick answer: You should include them, accessibility features expand who can play your game, are increasingly expected, and many are low-cost to add. Start with high-impact basics like subtitles, remappable controls, and colorblind-friendly design. It's both the right thing and good for reach.
Accessibility features make your game playable by more people, including players with disabilities. Do you need them? You should include them, because they expand your audience, are increasingly expected, and many cost little to add, and because making your game playable by more people is simply the right thing to do.
Accessibility Expands Who Can Play
A meaningful number of players have needs, visual, auditory, motor, cognitive, that affect how they play, and accessibility features are what let them enjoy your game rather than being shut out. Subtitles, remappable controls, colorblind-friendly palettes, scalable text: each opens your game to players who'd otherwise be unable to play.
So accessibility isn't a niche concern, it's about a substantial population of potential players. Including these features expands your real audience, and excluding them turns away players who'd happily play and pay if they could.
Many Features Are Low-Cost
A common misconception is that accessibility is expensive. Many high-impact features are actually low-cost, especially if considered early: subtitles, control remapping, colorblind-safe color choices, and text-size options are modest to implement and benefit a wide range of players, including many without disabilities.
Building these in from the start is far cheaper than retrofitting them later, so the cost argument largely dissolves when accessibility is part of your design from early on. The return, in reach and goodwill, is high relative to the effort for these basics.
It's Increasingly Expected, and Right
Beyond reach and cost, accessibility is increasingly an expectation, players, press, and platforms increasingly look for it, and its absence is noticed. And fundamentally, making your game playable by more people is the right thing to do, a reason that stands on its own regardless of the business case.
Start with the high-impact basics, subtitles, remappable controls, colorblind-friendly design, scalable text, and expand from there. So: yes, include accessibility features, they expand your audience, are increasingly expected, and many are low-cost, especially built in early, making them both good for your game's reach and the right thing to do.
