I first joined the hobby in 1982. Now I write my own historical RPGs. History is my thing, I graduated with a degree in Ancient History and have written four history books as well as GURPS Atomic Horror. And I'm a Gibson-loving cyberpunk at heart!
Anything historical. I collect Roman pottery fragments as well as fossils from the local beach. I read history, I write it. As far as Fantasy and SF - I don't read any, and my favourite movies are the Aliens series. Cyberpunk - see? Love that Giger!
