At a glance, this would look like a cheap hentai racing game with Atari 2600-style graphics where the girls aren’t pictured. And it is. But the one thing that stands out about it is that the game is exclusively 2-player, with the losing player’s girl stripping with every race she loses. You’re then given points to power up your car’s speed, handling, tires etc. for the next race.
