All my articles about Street Fighter HD Remix are now in one handy place, accessible from the top navigation bar and at the easy-to-remember url www.sirlin.net/sf
There's 17 character balanace articles, plus the introduction, the feature list, and the complete change list. I revised and updated every article, so consider this the definitive repository of SF HD Remix information. Together, these articles are longer than my book, so that's a pretty incredible amount of information about the game's design. Enjoy.
