Session Zero is a promising new zine for the DW community. There has been some silence around DW fanzines for a while. I'm glad to see that Brian has taken up the gauntlet to create something new.
The setting idea is fresh and offers some appealing opportunities for players and the Game Master.
The author delivers a well-rounded package for setting creation. There are enough tools for the Game Master to get up and running in no time. I can imagine that some of the ideas can be useful for other fantasy RPGs, too.
Session Zero follows DW's adage to ask questions and build upon the answers. If your players are not up for that, some of the material of this zine falls flat. (This is not the zine's fault though. Just something to be aware of. Make it clear to the players that you need their input.)
Brian could improve the organization. The artwork has a homely charm but is not superb. If you want to help, you can head over to the patreon to raise money for more artwork.
The zine is PWYW and packs a punch for (basically) free.
