Although Varicella regularly gets high marks, I've never been able to enjoy it: it's of the "die many times in order to learn what you have to do" genre, you'll die many times not learning anything first because you're in the wrong place at the wrong time, and even knowing what you have to do you'll die many more times figuring out how to execute it correctly. As such, there's too much drudgery here for me to enjoy the play of the game, and the time pressure takes away from my ability to appreciate whatever worldbuilding has been done. To many people's taste, perhaps, but not to mine.
