Before I start critiquing, let me state that I really really like Mutant: Year Zero. A lot. And the game system. And the upcoming RPGs. Especially the rumored fantasy one. Tales from the Loop looks fantastic.
One the other hand, I am prepping for a Mutant: Year Zero campaign. I became a bit frustrated due to the changes mentioned in Genlab Alpha that are not in version 2 of the PDF for MY0 (with some being listed as changes but not making it into the text of the PDF). I finally bought the PDF of Genlab to get the updated rules.
I would really like to see a version 3 of the Mutant: Year Zero PDF with the updated rules for NPCs and mutations (starting MPs for NPCs), initiative, grappling, and recovery. And maybe updates for the skill Inspire for the Chronicler (not sure if that is official)? I like all of these changes but it was difficult to even know about the changes and actually get the updates. And maybe an errata sheet? I have the physical book and created my own errata sheet.
Love the game. And the system. Just want the best rules to use while running it. Thanks!
