Rather than having artists spend time on detailed character designs, in this Japanese simulation dating game, you're able to plug in photos of celebrities or your crush and pretend to romance them.
The Mousou Mansion game by GimmickPlus is set in an apartment building and gamers play as the female protagonist. Since there are no guys drawn into the game, it's up to the player to provide a photo to upload in order to make the story. Naturally, this can have pretty funny results, especially if you choose an animal, pop culture characters or even a food item to romance. Although the Android app is definitely aimed towards female gamers, the potential for hilarity makes it have a much broader appeal.
