A question, how does the God machine fit into the platonic reality of Mage the Awakening?
As the ramblings of a deranged person who saw something that man was not meant to know or understand and can be used as a plot hook for just about anything the ST wants, like it was in nWoD First Edition. Trying to fit the God-Machine into a game that isn't Demon in any other way is going to make people sad. The God-Machine as presented in nWoD 2E works great for a Demon-primary game and just kind of... doesn't work at all for literally any other type of splat or type of game. Thematically, the God-Machine is anathema to a lot of the themes of other WoD lines, because Demon is not a game about humanity, not in the sense other nWoD games are. It's a game about state power and about espionage and ideology and politics and the awful things you do in service to all of these. There's a reason that the Demon 'morality' stat is Cover, rather than an actual 'morality' stat.
And for a lot of splats it's even worse because they're not designed around the God-Machine and what it can do. It's a singular entity that is incredibly setting-consuming because it has relatively few internal conflicts, it acts on a very large scale, it has the mundane powers to make anyone's lives incredibly fucking miserable without spending much (if any) effort, and if you piss it off enough it will send Seraph Team Six to murder you and everyone you love. Most splats don't have the ability to literally cast their lives off and take up another one-even Mages have it rough there.
