I'll look onto that Cubivores..but I definitely had my share of weird (but fun) games.
Try Chulip (PS2). Your goal is to kiss the girl of your dreams in this one town. And you can kiss everybody in town. Of course, their reaction depends on the situation... Really funny, Japanese humor on this one.
Also, if you can read Japanese, try Vampir for the PS1. Leonard Di Caprio FTW!!
