Well I believe when most players talk about new content, they mean new sex animations or new X-Girls like Jean we voted recently.
So far until my games crashes (I don't believe I'm spoiling a lot but still be awarned...) I noticed now MC addictivness seems to be effective with every girls not just Rogue with new scenes. So they'll regulary "come" after you as Rogue did... which can be annoying sometimes... and it seems to be unavoidable, that triggers automatically from the moment you met the girls, except with Emma where you still need to "catch" her. And I tried to be "mean" with her but they always get back...
I personally would prefer more side content and especially
especially I would love to see more content unique to each specific girl. As it stands right now, they feel more like cardboard cutouts with next to no variation except for looks and their respective posing during sex.
This is not variety, at least not on a gameplay level and just barely on a visual level. If all you do is the same one or two tasks but with different looks to it, it doesn't take long till these tasks feel repetitive and boring. It's a quick burner in that regard: You can (or could, before shit broke down) achieve many steps with the girls within a very short timespan, but that leaves little further room to explore and enjoy as some people (myself included) tend to drift towards the path of most payoff, not what is potentially more enjoyable for oneself.
So at least for me, side content like the shower walk ins, girls taking initiative for once and the pool (however badly that has been handled on a visual level) were some really nice refreshers that gave more life to the game. That is until I once again noticed that all girls behave exactly the same at the exact same levels...
