Well, Christmas is over...but the fun certainly isn't. My wonderful wife got me one of the most fun games for our Wii. I don't play guitar. I don't play anything except the radio, actually. But I love Guitar Hero!
The game is just fun. It took me a little while to get a feel for it, but I picked it up pretty quickly. Shelsy and I play together, too...it's awesome. I fully recommend it to anyone. :-)
Right now, I'm a pretty solid medium player. I've gotten through a few songs on hard, but I'm not all that great on it yet. I'll get it, though.
So if you've been thinking about giving it a try, I say definitely go for it. It's an ultra quality game. :-)
