If Titanfall sells 3 million combined on Xbox platforms and royalties to the platform are 20%, that's 36 million dollars. Add in whatever additional consoles it sold extra and the dollars those console owners will spend over the generation, and add in ancillary money from DLC platform fees and Live accounts and the like, and MS easily got the rumored $50 million worth in loans and funding it gave EA/Respawn.
I mean, the marketing budgets for these consoles are huge, and you can't begin to put a price tag on the extra PR push it gave the console. They could easily be dead in the water without Titanfall ending up in their stable. I still think Titanfall moved a lot of consoles in the launch window - - people buying early knowing it was coming and helping them pull the trigger on the X1 purchase. I know it was a factor in my getting one at launch, even though the game came out so much later.
