1. If i am honest, in my humbled opinion, they should forget this fancy stuff of multiplayer rooms, harem, online likes, whatever. The simpler, the better. I do want to control the whole scene on my own. Adding more models to a scene, setting actions, maybe the camera, items etc. would be fun.
But i do not need others for that! The DRM is another thing they do not need to talk about. Just make a version near 1.0.
2. Several people are asking about basic features, e.g. outfits, positions, fluids, ... and more kinky stuff. So, I do not get the point about referring to a new model (the 4. model) or a brand new mode (point 1) or fancy stuff.
Combine the old and the new game - voilà!
What would you say about a free run mode within such a combined game? A dancing model or walking model in a common room e.g.
3. It is all about fun!
And the fun is cut down now by encountering faulty positions and flawed models in some positions: Half ass missing in one position, breasts not interacting with solid stuff, or half model in a position half buried in the floor) - This is not fun, the visuals and models are amazing though. This is why many of us may be lurking here.
Even non-touching natural animations can make the game way more interesting, and they will be necessary.
I guess more sexy moves or actions such as taking a shower would be a fun part.
And this has even not to be "interacting". The next level with interactions as well ... A further multiplier of fun!
So, what game would it be all those features combined?
