I finally achieved being the top 25 overall GHWT drummer worldwide for the Wii. This is based on carreer which totals all your scores up. I believe I just hit around 29 million points. Most of my scores for individuals are easily top 100 if not top 50. My best rank is Rambling Man by the Allman Brothers: Rank 4.
The only song I cannot beat on expert drums is Hot for Teacher by Van Halen. I'm going on slow in the training mode and picking it up slowly lol.
I guess I could lose my placement if I don't keep on playing actively but I think it's safe to say I'll be in top 100 for the whole lifespan of world tour :D
Now, only if I could get GH: Metallica with another bass/kick pedal and play Expert+...
EDIT: (1 day after blog post) - I passed hot for teacher and got a 4 star this morning. It's not even that hard, I got it in my first try. It's just the 40 seconds of the introduction that is pretty difficult. Went to rank 21.
