If Xbox Play Anywhere is going to be removed from key points because its also listed under Availability, it needs to also be changed on Gears of War 4 for the sake of consistency. Id argue its more of a key point and that the reference was useful information for the user and its removal was a detriment but *shrug*
Edit- I see Xbox Play Anywhere does link to a PCGW glossary entry describing the service so my point about the reference is null but the prior still stands.
Also checked all other Play Anywhere title articles just to ensure consistency .
