Eric has tweaked the new Board Game rules presented in the Circuit Guide, see this post. He has also added a faster variation, allowing a fighter to rise in Rank quicker, so there are fewer fights to get to the World Warrior level.
There have been some updates to old Punho do Guerreiro (Warrior’s Fist) issues, the Brazilian fanzine for Street Fighter RPG (SFRPG). The updates are about streamlining ways to represent traditional fights, definitely worth a read. 🙂
