Accessibility is, or ought to be, a very important topic for serious game designers. Accessibility issues can be left in the dust, though, in the excitement of developing game play.
To help us all address accessibility in our products, the Human-Computer Interaction Lab in Heraklion, Crete have put together a game for us (! how often do we get to design games for ourselves?), called Game Over! Actually, it's a series of game episodes, each one highlighting a different accessibility issue through non-example in game play. It's clever, and effective - and it's in English.
Many thanks to Mindy Jackson at enspire learning for bringing this to our attention!
I'm serious,
Anne
