The Lovers: John and Jane

"You'll follow my first directive and remove your clothing!"

Alright, this one's a bit of a gag inclusion - the game is a softcore porno made interactive through menu selections afterall - but it earns its right to be here through its use of photo slideshows rather than rendered graphics. If you want to talk about realistic romances, it's hard to get realer than the real-life shots of John and Jane gettin' down.
