It's erotic in the context of what's happening in the place & time. It's a matter of personal taste but to me there is no erotic charge in a son lusting after his mother but many fans are playing this game for the incest. Until people started having a jab at the blackmail, I had nothing to say on either subject. Now I find I'm posting about the Aiden path regularly, even though it's far from the only reason I play AWAM. Instead of speculating about where it could, (& probably won't) go, many posts seem to express disapproval in some form.
Every single adult corruption game I've ever played contained coercion. This was usually of a much cruder, straightforward type than has so far featured in AWAM, which up to now has been blackmail with a vanilla flavour but has still managed to be erotic. Just as it could be wondered as to why I play a corruption game containing incest, (which I avoid when I can), so it could be mystifying as to why the coercion factor has not been taken for granted in a game of this genre & pulls in so many negative comments. It's an integral part of the theme folks.
There are so many options available for those who find it too much, from never starting it at all, to myriad ways of ducking out of it, with more to come. Incest is MUCH harder to avoid. Even I didn't grasp when I started playing, just how important an aspect it would be. I understand that people all have widely differing tastes in the AWAM fanbase but here's the thing..... I like the blackmail. I find it erotic. I'm never going to apologise for that. I'm here to indulge in dark fantasies in an entirely fictional world, as are incest fans. It doesn't mean that either of those branches of the fanbase would take part in such practices in reality. I will not be kink-shamed, have blackmail labelled as toxic, or otherwise sit back when some of this story's best bits (IMO), are under attack. Nor will I do what I've long considered, ie drop in to make some disparaging remark about the incest, in the style of the blackmail critiques.
Playing AWAM, whether for incest, blackmail, or anything else, does not make any of us greater sinners than we already are.
