There are traditional selling points for erotic games. You know, things like boobs and boobs and also boobs. "Real Kanojo" ("Real Girlfriend") has boobs, sure, but it also has face poking and cheek squeezing.
This is innocent enough.
This just seems painful.
And cruel! Sadness.
The game also offers widespread, 3-D and even webcam face tracking. Check out the game's real time trailer, but note that it's probably NSFW. You've been warned.
