Beastly
This was pretty fun on the Sega Genesis, but I'm sure I'm missing out by not having played the arcade version. Though, in retrospect, I probably saved myself about eighty pounds' worth of quarters. Did you know this game is HARD?! Maybe I'm just a wuss, but by the time I get to that level where the yellow guys with the pointy scrotum-stingers are running full-tilt towards me, I'm panicking and praying for the quick release of death. Never beaten it, probably never will, but won't stop trying! I'm a sucker for punishment. Or, in this case, bestiality.
