I don't really do much marketing, that is true. I've put more effort into the other direction -> reducing my requirements. I've grown to require less external input in any form - and that is something I would recommend every indie developer to cultivate.
While, as an ideal, I think that's something certainly worthwhile to aim for, as the saying goes "no man who's a man is an island." In my perspective, we are very much so dependent on external output as it can be a good predictor of the general appreciation of one's game.
I realize the title page controversy was disheartening for you but I hope you won't withdraw in a shell and become non-receptive from external output. I think other people can help us see things we can't see from our own respective perspective. I personally didn't find it shocking but I can understand people could be. It's ok, different strokes for different folks. The ess traditional and politically correct something is, there more chances some people will bare their teeth at it as it shocks their respective sensibilities. Just my opinion of course!
It's cool that you're zen about this and happy with the results. If you're satisfied, it's all that matters. Do keep in touch about your next project however!
