According to a recent NeoGAF thread,  It looks like Tomb Raider sold 60K units in its first week, Xbox 360 accounts for 15% of total sales.  Rise of The Tomb Raider is a timed exclusive for Xbox and Fallout 4 came out in the same week selling 12 million Units in it’s first day. The UK only have gotten Rise of The Tomb Raider on November 13th. So that’s some of the reasons it didn’t go as expected. Stay tuned for more official updates
