It's your game, but that feels like something really important to just ignore, no? For an optimal playing experience, would you not want to be invested in as many of the followers as possible? It is really unfortunate, I'm probably going to refund it on Steam. That isn't even supposed to be like a threat or anything, I just don't really jive with Cuckoldig/Pimp stuff, but it's semi-required for certain aspects of the game if I want to play the game how I want. There probably should've been a setting to turn off NSFW/Lewd actions for Courtesans, would've been a simply fix, but that's coming from a guy with no dev experience so maybe I'm wrong. Regardless, it's genuinely unfortunate because I really liked the look of this game, but if there's no work around for something as simple as this, then it's just not for me.
Wish you luck on all current and future projects.
