Good Colonel,
I thought I should mention that my parents are
still angry at you for writing the AD&D books and corrupting me at the tender age of 10 (already 24 years ago -- sheesh!

).
Seriously, I cannot express what a huge influence your work has had on my life. I know AD&D is just a game, but it compelled me to read quite a bit as a tender child (and learn to use a thesaurus!), use math skills, write detailed notes, develop problem-solving (and problem-creating!) skills, and exercise my imagination in coming up with new worlds and adventures for my friends. At the time it was all 'just fun', but in retrospect, I see that playing those games served a vital role in my intellectual development. Plato states in
The Republic that the key to educating young people is to make the process of learning seem like 'a fun game' and not about 'dry, important information' (or something like that -- I don't have the book here

), and AD&D certainly did that for me.
