Why do a timed exclusive for Tomb Raider

[Captain_Yuri]

Cause MS paid enough to make it worth it... Like, when they launch a game, the need to sell blah amount of sales to break even before the rest can be profit so if MS paid for that or close to that, I think it makes sense as to why they did it cause guaranteed money is always better than potencial money... Plus its timed exclusive so they aren't losing too much
