Fun Fact: pretty much no owner of a non-porn IP likes to see porn parodies of it*, because of course they don't, as porn is stereotyped as "non-respectable" (and yes, huge numbers of people who think that consume porn anyways, humans are hypocrites like that). GW is probably a bit more proactive than most about this, which stems from many legal troubles defending their IP (many of those troubles being self-inflicted of course). You can bet the only reason there are still porn parodies of stuff like Avatar or Marvel & DC is because someone somewhere decided that siccing the legal department on them was not a winning proposition (parody counting as protected free speech, Streisand effect, devs are Russian or otherwise out of reach of legal recourse, etc...).
In any case, I'm happy to see a 40k porn game, even if it's with the numbers filed off. Art looks fantastic.
*Except the Japanese, who seem to have a much higher tolerance for such things.
