Rebecca Saltsman, co-founder and CEO of Finji and developer of Overland, had an interesting experience when she was demoing the game at PAX East. A show-goer came over to the Overland demo booth and said they really wanted to play the game, but couldn't due to their Dyslexia. Apparently the way words were shown on screen was "too frustrating." That's all Saltsman needed to hear to know she wanted to fix things.
"I was fascinated by this. I wanted to make Overland accessible. So I asked a lot of questions. I know the science of dyslexia, but at that point I didn't know the accessibility options. I came home and asked Adam [Saltsman, director of Overland, and her husband] to put this feature on the dev schedule." And he did - it went in the game."
In the side-by-side comparison above, you can see the game using standard text on the left, and OpenDyslexic font on the right. The subtle changes in font helps address "contrast/blindness, letter confusion or rotation, and crowding" to make for a better experience for Dyslexics. It may not look like much to most eyes, but it makes a world of difference for others.
