I know it might not mean much, but other games he's played since XB1 came out in order of most recent:
Bolded are ones not BC yet. Given all of his older games except TR have been BC and that he's testing BO2, the list might be worth looking at. The only one that doesn't make sense is GTA V and Watch Dogs (But he played WD1 when it came out on XB1, so it's weird that he went back to the 360 version..).
