I'm severely dyslexic and to a certain extent overcoming it is a matter of self control. Reading and writing were very difficult for me in elementary school but I overcame it to where I am a functioning member of society by years of hard work. Sure it is easy to make excuses for what ever genetic cards you were dealt but that really doesn't get you far in life.

The best free, browser-based, adventure game based I've played in a while is Immortalix. The owener is constantly making updates and changes. http://www.immortalix.net/

I would think instead of using a VHS tape or DVD the video would just be stored to a hard drive for say a week or month and then recorded over.
