As with any console launch, the first wave of games for the Xbox 360 are going to range from the great to the mediocre (or worse). What are the best and the worst launch titles that you have played so far? Use the comments below to list one (and only one) title in each catagory. And for those of you that don't deal in absolutes, you may give a 1 to 10 ranking (no decimal points, please).
Here's an example:
Best: Call of Duty 2 (9 rating)
Worst: Tiger Woods 2006 (7 rating)
