Yes Squirr3l_Ma5t3r, I am totally addicted to this game. Not only do I jam at home, but I bring it over to my friends and we all rock out together! This past weekend I think I made another GH addict (a cute girl at my bud's Halloween party!) We mostly played the 4 song GH2 demo and I'm totally stoked for the full version next Tuesday. I'm going to attempt to pick up the 10 song demo before this weekend.
Also don't you fret Xbox 360 owners, GH2 has been confirmed to be released, probably Spring '07. One really cool feature is that you'll be able to download new songs from the Marketplace. Here's hoping for online multiplayer! (Although that would probably be really tough with lag and what not.)
