Variety in how the deal goes in cells is certainly a major issue right now, they do feel repetitive from conversations, to order of doing stuff, even girls' reactions are almost the same. The only noticeable difference is probably Vixen.
There is also kinda a problem because u can see this all over this forum u have a hardcore no ntr crowd and u have people who like or are ok with ntr and its hard to make a game that would be appealing to both, especially to those who don't want any sort of ntr what so ever. And a shift to more of a cell content do tell what side is actually winning or bringing more money.
In my own opinion, bordello and strip club didn't need to be separate entities bordello is just a natural progression for a strip club and u could still do it all within the strip club. I have mentioned this before and i still stand before that i think that strip club in particular needs more content, u need to have stuff like lap dances, and this is where i think that bordello is unnecessary, lap dances could have easily evolved into lap dance with bonus and this could be Lex or ntr content.
if you think how much girls there are, and how much content u need to add just so that every girl gets complete cycle its easy to see why the stuff is as it is, even if he added no more girls until he finishes the ones he has, and if there were no more gimmicks like prison or yacht at this pace you would still need a hell of a time to do all of it, let alone expand on what u have. This is going for years now and it is probably going to go on for years as long as he can make money of it. I do think that over time this game will probably change from what it is now, like it did several times already.
