Last week, Xbox Live announced its schedule of Games With Gold for December, bringing to 48 the number of free games it offered in 2016. Were they any good? What would they cost otherwise? In short, what do the numbers say about the value of this Xbox Live Gold benefit?

We’ll try to answer that question this year as we have the past three years. To that, however, we’ve added a few more questions: How old is the game? Did Microsoft publish it? What publisher did Games With Gold use the most? Did these appear earlier on PlayStation Plus?
