I didn't actually get the Rock Band deal, but that has to be the best deal listed up there. I used the EB games Buy 2 get one free though, but my vote still goes to Rock Band at Toys R Us.
For me it's between Grand Theft Auto IV and Fallout 3. It's pretty close and I do think Fallout has much more to do, but Grand Theft Auto felt like a great action movie and had me coming back and playing more. They also created more characters that you care for with Niko being one of the most...
