I have discovered today that it is quite difficult to play Guitar Hero with an injured pinky finger, particularly attempting the final tier of songs on Hard.  Continuing work on my 5-star set on Medium was much more achievable, since the pinky can pretty much sit that one out.  But there was just no way I was going to get through "Institutionalized" without being able to feel the buttons.

Still quite enjoying the game overall.  Hopefully I won't have to buy a new guitar for Guitar Hero 3, though the prospect of a wireless GH controller may be tempting enough to talk me into my 5th guitar...
