What do you want from this game?
I want to see a wide variety of different looking sexy player avatars fuck eachother in creative ways, all of us into different kinks and coming together to revel in our sexual fantasies.
What would make you subscribe?
If I won't lose nearly everything when I lose premium, since I hate how much it feels like renting access to what you've grinded for in an account. I'd vastly prefer being able to permanently unlock a few poses and such through one-time payments, but I still might budge on the issue of subscribing if they let us customize women avatars bodies more, make better avatar profiles, and show the players some kind of schedule that lets us see what they're working on releasing ahead of time.
Stuff not relating to sex is mostly uninteresting to me, unless it indirectly leads to it quickly.

Like, say, extremely slutty clothes or a bar with a strip show. (Being able to dance on stage for others to view would be perfect too- like another brothel option, getting money from tips?)
Do you find ingame tools satisfying? (menu, npc dialogs)
For menus and npcs they're a bit simple, but work well enough. For talking to other players, yeah, still a bit lacking.
What about ingame prices for sex scenes?
Not interested in most of them, since they're a bit too close to the regular stuff from the other MnF site. I'm more interested in what the players themselves can do. The npcs are just extra eyecandy. Bit of a shame how so much of it is petnis action. I know how it was supposed to be a cool premium thing, but if I had a male avatar, I'd like them to be fucking the npcs, not the toy dildo. Women should be able to use the petnis on themselves instead as a bonus scene. Or every premium member being able to use it for threesome action, even when they lack a third partner- if they add that later on.
What do you think of the way cash is made? Do you think your income should scale with your sex level?
Another minigame would be nice for variety, but its pretty easy to grind cash right now. Not many ways to spend it, tho, since npc scenes get stale fast. Renting rooms is nice, but that's not generally something a girl needs to spend on. Scaling with sex level? Nah, not unless they add something where you get paid for actively using your own advanced sex poses.
