Any other games like this? Apart from fallendoll
Depends what you mean by like this?
There are games in development that target higher end systems like wild life, carnal instinct, home together, under the horizon, our apartment and probably some others I've forgotten about. They are in various states of development mind you, none are near release but they're all further along than this title.
If you are specifically looking for the xeno genre I don't think there are many, and definitely none with decent graphics.
Meanwhile if you're just looking for a sex sim illusion titles are probably your best bet. They aren't "like this" in terms of what this game is
trying to be, or at least advertising itself as, but they are basically a far more fleshed out version of everything Helius has implemented so far. Essentially high fidelity sex sims with a lot more features and customization than you'll find here.
