I too experienced Raving Rabbids because of a girl, the first one was just disjointed and as Brobzoid notes you had to unlock everything before you could play them with people. I heard the later games were better but never bothered.
Some of the mini-games were just maddeningly horrible though we worked out a system where the seemingly obvious tilt puzzles I could not for the life of me do she took care of and I whipped through the FPS "boss" stages. There were still some where no matter what, nobody we knew could seem to figure out the controls properly.
But slapping those damn rabbid choir kids or whatever became quite the hit.
Just to throw in more of my opinions that nobody cares about for the last few pages, I'm fine with the Wii. I've already proclaimed my undying love for Order Up!, drunken and even sober Wii Sports/etc. wasted many hours with friends, and I liked Galaxy, Metroid Prime, having one thing hooked up for GCN games as well, plus things like de Blob, etc. enough. Of course I just play games I like rather than fret much, and plus I have a PC for everything important like Saints Row: The Third.
Also, without the Wii I would have never spent that entire two hours beating all of Food Network: Cook or Be Cooked. Despite my cuts from the jaggies.
