Basically, this is a game I could never, ever beat as a kid. It has a ton of gory graphics, etc. and it's beyond unfair. ...But we don't even get that far, because it's also a chore to do combat in, which is a big part of the game.
I'm actually considering trying something special for this since it's on my "To Finish" list. We also did the sequel that night.
