Las Vegas is a Japan-exclusive graphical variant of Softporn Adventure, and hence can be seen as an earlier version of Leisure Suit Larry, which was released a few months later. The gameplay is, by and large, identical to the original text-only version, with the exception of a few adjustments made to the monetary system and a few commands handled slightly differently. Like before, the player types text commands consisting of combinations of verbs and objects. The game recognizes both Japanese and English inputs.
