I finally beat Raining Blood on Hard (if only I'd known at the start that all I needed was a large bottle of cider) only to be confronted by the last boss battle, which has now squared the amount of non-fun of reaching the end of the game. I guess the trick is to save the power thingies. In the meanwhile, I've done about 20 songs on Expert.
The one thing that would really make a Patriots/Cowboys Superbowl enjoyable is an asteroid strike. Sorry, Alex.
