I am to the point where I solely play on Expert. However, unlike every other person, it seems, that has posted in this thread, I can beat every song on Expert relatively easily at this point.

On GH3 I've FC'd about 10 songs on Expert. 5 stars on all the regular songs except for Raining Blood, which I'm about 10k away from 5-starring.

I'll give you info on GHWT in a little over a week, when I finally get to play it.
