After playing 18 hours of "Frets on Fire X" for two days, I'm still up to it. It doesn't matter that I play on easy. Metallica's One still kills me on easy. An excellent way to spend the first couple of days of your year. And yes, XBOX360 and PS2 guitars work well with this. I wonder how long it takes for the FoFX team to get sued by Activision or Harmonix.
BTW: After hearing Joe Satriani's If I could fly for the 20th time, it still doesn't annoy me.
After 98 hours of gameplay of Fallout 3 and third time playing since 22nd December, I'm still hooked. I don't understand why.
Happy this year and good luck with your life this year.
