Hi
BrokenKnght, thanks for the submission and sorry for the delay. We have added the flags as you suggested with some minor changes. For example: All Xbox One games require an online connection in order to unlock achievements. That's why all Xbox One achievements get the Online Required flag.
We have also attached some extra Collectable flags to some of the achievements.
If you have questions or notice some flags that aren't quite right, please feel free to resubmit.
Thanks again for your input
