Normally NPD numbers aren't worth 3 separate posts, but only now has Gamasutra put up the full top 20, which shows the positioning of Fable II and Fallout 3. Both titles were released in mid-to-late October, which meant they were never shooting for top-10 spots in November.
Fable II went from #1 in October to #19 in November, while Fallout 3 went from #3 in October to #12 in November. Nothing terrible, though it's not saying too much without exact numbers.
