>Maturity is the ability to respond to the environment in an appropriate manner. This response is generally learned rather than instinctive. The outdated ideas about sex and sexuality – and they are outdated – that Slaanesh represents are simply not appropriate for the game any more. They’re not appropriate for younger gamers; they’re insulting to women, to trans and intersex people, as well as to any man whose sexuality extends beyond five quick pumps whilst thinking of England. The mature response would be to acknowledge this, and avoid the instinct to avoid change. Change terrifies people, especially members of the geek community, who loathe retcons with a passion that could eclipse suns.
>But, in my opinion, Slaanesh shouldn’t be part of things as they are. So how could we deal with this?
>Well, contrary to what you might think, I don’t actually believe we should Squat it. For better or worse, Slaanesh is a longstanding part of things, and it’s would be simply unfair to those gamers who’ve got Slaanesh armies. As well as this, 40K isn’t just a wargame any more; Fantasy Flight Games’ excellent lines of tabletop RPGs enable the discussion of some very mature themes, especially in more investigation-based games like ‘Dark Heresy’. A Slaanesh cult could be an intriguing way for an appropriately mature group of gamers to look at all kinds of ideas to do with the aforementioned sex, sexuality and other adult issues.
>So what to do? Well, in my opinion, the best solution would be to ‘retire’ Slaanesh as a GW-produced faction and make the army Forge World’s property. If you’ve not read any of FW’s books, I can attest that they have demonstrated time and again that they can do nuance. Not to mention, FW’s models are NOT targeted at children, but explicitly as adult collectors, meaning it’s possible to completely ignore that issue of inappropriateness. GW as a company can completely take advantage of this, having its cake and eating it, and they should. Obviously, this does nothing to overcome the inherent problems of sexist models, or the deeply embedded homophobic and transphobic imagery, but that’s something which can be looked at over time in Black Library books, Forge World supplements, and FFG RPG supplements.
>Slaanesh has already been replaced by the Horned Rat in AoS, which clearly shows it can be done in 40K too. To be honest, this is the ideal opportunity to do something exciting and new for Chaos players, giving them a whole new Chaos power to deal with. They could bring back Malal, or they could choose something else to fill the gap more naturally. Either way, it would be a step towards turning 40K into an actual, truly mature environment, and that can only be a good thing.
