One of my favorite Actionscript game programming blogs is http://www.emanueleferonato.com. He has been around for quite a long time, and when I decided to go into flash/actionscript from C++, for game programming, his old posts were invaluable.
Check out his book, if you’re interested, let him know, or pick up the book!
$25 for the ebook, I’m going to buy+read it, and next week post a review. Surely another great book to add to your collection, from one of the internet’s experts on Actionscript game programming!
