I wouldn't put them on equal footing. One is a relatively successful IP that hasn't really sold more than 1-2m each iteration and the other is fucking Street Fighter.
This smells of paying to keep it off X1 rather than funding development.
Uh, what?
Tomb Raider 2013 has sold over 6.5 million units, including the definitive edition.

"TOMB RAIDER, released March 5, 2013 has received over 70 “Best of” nominations and is the fastest selling game in the history of the franchise with more than 6.5 million units sold."
Not sure how you think Street Fighter is a bigger deal than Tomb Raider.
EDIT: Oops, disregard, I thought you were comparing this deal to the TR deal, not DR3
