Der er åbenlyse fordel for Xbox at købe Activision Blizzard, fra at kunne profitere fra Call of Duty-serien til at tilføje en masse værdifulde spil og serier til Game Pass. Men spørger du Microsoft selv så er det også grundet deres succes på de mobile platforme i form af Call of Duty Mobile, og Candy Crush ovre hos King.
Faktisk mener Xbox-chef Phil Spencer, at Xbox kunne gå hen og blive "irrelevant", hvis ikke de etablere en bedre tilstedeværelse på de mobile platforme. Han siger dette til GameSpot:
"I am really looking forward to learning on mobile. The truth of the matter is, if you're going to continue to be relevant in gaming at a global scale, you're going to have to find a way to be relevant on the largest platform, which is mobile. It's critical for us to deliver on the full promise of over 3 billion people playing video games; the opportunity to reach more and more people. People who only play on their phone, find Xbox to be something that's interesting for them,"
Han har tidligere sagt at det ikke betyder at de vil forvandle alle deres serier til mobile spin-offs, men succes skal de finde, siger han.
