The game has great character customization functionality and very simple pose creation interface, but it has very poor default graphics, because it was development under directx8. The mod is based off of an old 3d sex simulator, which allow to you select up to four characters, select some scene for action and create some static or animated pose. There's even a 'QuickMode' just for fun that loads your model in a randomly selected room waiting to play with you. Officially, TK17 is movie-maker software, but most users enjoy simply playing around with the individual components. TK17 is an easy-to-use 'sex simulator' that allows you to construct your own custom models, apply custom outfits, design animations ('Poses'), and test them in dozens of locations ('Rooms') to create your own adult movies (ie: 'Sequences').
