Sorry chief, that's not allowed. GW foresaw that plenty of fans would just sidestep the whole concept for their army, so not only did they launch Rowboat's crusade that categorically reached every extant chapter, yes even Little Billy from Idaho's homebrew one; not only did Rowboat personally speak to every chapter master and instruct them to accept Primaris, but, even if you *thought* a chapter like, for example, the Black Templars - formed explicitly in response to and in order to ignore the Codex - or your own chapter that you wrote the fluff for would distrust Rowboat and refuse his "gift", tough figgins, the Emperor personally instructed one of his Custodian Heralds to go out with Rowboat and tell every Marine chapter that accepting Primaris was a command direct from Him.So it's Primaris, or you're now a Renegade, assuming you managed to survive being attacked by Rowboat and his merry men when you refused.And that's why I pretty much walked away from GW's fluff entirely - they already got rid of the fantasy setting I liked, and the reason why is the same reason for the M42 plotline for 40K and is perfectly exemplified by the Primaris Imposition: control. Not in some sinister "ermahgerd GW r like controllin ur mind wake up sheeple!" conspiracy nonsense, but simply in that they want to move away from the idea of a setting that we all participate in and contribute to and have our own little versions of in our heads, to a straight up ongoing story with Big Damn Hero characters they can sell you models of. Going forward it's not going to be stuff like Armageddon or the Imperial Armour books where you can just ignore it if it doesn't interest you, it's all going to be big bombastic stuff featuring the named characters of GW's creation and you either like it and play along or you get nowt. My view then becomes that if they're not offering me anything, they won't be getting much out of me in return, but I'm evidently just a crusty old grog because they're making money hand over fist so evidently the "Saturday Morning Cartoons for Teenagers" model works for themEDIT: The art is really nice though, I'd buy that over the Aggressors any day of the week.
