Yes or No? I downloaded the demo off of my Wii WiFi and tried it out. Anybody bought/tried it yet? I am wondering if I should get this game. I already know that my sense of rhythm is rather bad so I can see myself getting stuck and frustrated halfway through the game and tossing it aside. I also can see the [addictive?] music getting stuck in my brain and hearing the music in my sleep. That is not good; the last time that happened I was hearing [Gamecube] Final Fantasy Crystal Chronicles music in my dreams and I was lost in that mushroom forest level and hearing that marimba riff over and over and over and over...
It's not for the easily frustrated. I had a bunch of problems with the flicking motion needed for stuff like the ping pong game. I really *wanted* to like it, and I'm sure that if you spent enough time with it you'd get really good.
You might also consider Elite Beat Agents as a good musical game.
The only reason you should get a core is if you get an excellent deal on it (to make up for the money you'll spend on a hard drive (about 100 bucks) and either a VGA or component video cable if you have a HDTV (about $30)
