Ok I know this sounds ridiculous, but I did say I'd ask this question to my friend who asked. I have a friend who is a massive history buff, but who unfortunately is completely blind (the only thing he can see are the brightest of lights,) I was telling him about CKII, and he asked me to find out if there was any way he could play it. Knowing the Game like I do I'm guessing the answer is no, but I did say I'd ask on the off chance.
