Kissing can be fun, but fundamentally it's a pretty gross human act involving the transference of saliva and tongues touching other tongues and whatnot. Realistic Kissing Simulator is a game that perfectly expresses how weird it is to kiss another human being. It's awesome.
It's starts, like many romantic encounters, with an innocent clasping of hands. After consent is given, the kissing begins: a weird, slightly unsettling tongue joust that ends with tongues in mouths and all the weird stuff that kissing entails.
Man, after playing this game I'm not sure I want to kiss anyone ever again. Don't get me wrong, I like smooching just as much as the next guy, but this has put me off for the foreseeable future.
(Also -- this game is really entertaining even though I have no idea what I'm doing.)
