Picked up GH3 at GameStop's midnight launch. There were about 30 hilarious gamer dudes out there - one guy had a huge curly white boy 'fro (I'm pretty sure he was at a different GameStop with me the night we got our Wii's last November).
I couldn't start playing GH's debut on a Nintendo console till after the Red Sox finished off the Rockies at like 1 a.m., but then I shredded till 3 a.m. The online play works perfectly. I ended up being ranked 252nd on the online GH leaderboard, but that was short-lived - I'm down to 800 now :( But I'll get better. I've played GH at other peoples' houses before, but I've never owned it myself.
It's cool how the Wiimote fits into the guitar to make it wireless, and makes sour note noises when you screw up and rumbles too. The PS and Xbox guitars can't do that! :D
GH3 for the Wii is an awesome game. It even has boss battles for the first time. I beat Tom Morello of Rage Against the Machine fame, but haven't gotten to Slash of GNR yet. I'd give the game a 9.5, but I'm sure most of the gaming sites that are tough with scores will give it closer to 8.5 or 9.
I also picked up the old GameCube game Fire Emblem: Path of Radiance, which is fantastic. I never knew I was so into turn-based RPG games. It makes me VERY excited for the Wii Fire Emblem game...
Well, back to shredding!
