Games Workshop offers the core rules for its Age of Sigmar Rules free for the downloading.
The guys at One Page Rules have created a one-page version of Games Workshop’s Age of Sigmar.
Age of Sigmar, Games’ Workshop’s attempt to kill Warhammer Fantasy, lacks even a basic points system. The rules allow each player to field whatever sized army they like. That doesn’t sit well with a lot of players, so the One Page Rules guys have come up with a points system fix for Age of Sigmar.
