I guess it goes back to my Father who, since he was a young boy, was Science Fiction crazy. I remember the bookshelves in the houses where I grew up were lined with Arthur C. Clarke, Isaac Asimov, Robert A. Heinlein, Ray Bradbury & many more. We watched all the Star Trek: The Original Series (TOS) reruns together. I remember Star Trek TOS as long as I can remember anything.

We went to the opening night of Star Wars: A New Hope together. I was 9 years old. I saw it 8 more times in the theatre. We also went to the opening nights of Star Wars: The Empire Strikes Back and Star Wars: Return of the Jedi. We went to the opening nights of the first 2 Star Trek movies too.

Along the same vein but on a different tangent I got interested in the Japanese cartoon series Star Blazers. My first anime series. Space Pirate Captain Harlock and Battle of the Planets (G-force) next.

Gamer. Bigtime. Yes, growing up we had Pong, Atari 2600 etc but I got into PC gaming very early.

Now, I'm mostly a hand held gamer whether it be my PS Vita, 3DSxl, my old PSP or my phone but I still game. 
A lot.

Am I a geek? I think so but there are many more Uber geeks out there that I don't hold a candle to.

I don't know everything about Science Fiction but I love so many genres of it. I hope you can see why I am the Sci-Fi Real Estate Guy.
