I like game design and now I want to study it as a hobby...
I'm looking for books, articles, blogs, sites, etc, but mainly books for me to buy, so I can read in the bus or something.

I could google search but I think it's better to ask you guys so I can get current info and different opinions.

Thank you.

FAQ 8: Books for aspiring game designers. http://www.sloperama.com/advice/lesson8.htm

Thank you, Tom Sloper, good article.

Still, what do you think about The Art of Game Design and Fundamentals of Game Design?

The Art of Game Design: A Book of Lenses is a fantastic read, IMO.

A Theory of Fun is a good one too.
