I just think its hilarious that a) you think these numbers are actually good compared to the original reboot, and b) that you think a console's install base can affect the sales of a game that dramatically.
Fallout 4 is up to over 2.5 million on Xbox One alone and it came out the same day. Tomb Raider, even when combining the fact the "over 1 million" number includes X360 sales, and the fact that it was heavily discounted during the holiday season (while Fallout 4 was not) sold close to one third what Fallout 4's sales were on the same console over the same time period. If anything, you'd expect X1 Fallout 4 sales to be lower considering that the game was also available on PS4 and PC, and the X1 version was the lowest performing version.
Any way you look at it, it is not good.
Shots might be fired, but they're from a dollar store squirt gun.
