This is super important so please do not discard.
We need our Spartan Assault achievements and Spartan Strike achievements from our iOS devices to be adding to our Xbox Live gamer score. I am standing up for us that have completed every single Halo achievement on every single Halo game except the Windows phone games. I don’t know how many people have done that but I know I am one of the people with 16,500 Halo gamer score. Think about it this way: you will be loosing money from people like me if you do not make all of the Halo phone game achievements linked. You would be losing money from me because I love going for achievements in Halo games. However the games are no fun to me when I know I’ll never truly have all of the achievements. That will make Halo so boring I will just stop playing it. Not everyone can afford to change their phone to get the remaining achievements in the Halo series. We will need the achievements to be counted the same on all phones as well. What I mean is instead of a total of 900 phone gamer score (two copies of each game) the total will be 450 phone gamer score (still two copies of each game). That will be the fair way of doing it. Please do this for your customers.
The phone games were designed for the sole purpose of pushing the Windows phone and Windows 8.1 tablets. The iOS, Android, and Steam versions were simply fan service, be happy that they made a port for you to enjoy. Besides, you do realize that almost every game on Windows Phone/ Windows 8 has Xbox Achievements right? Halo, Assassins Creed, Temple Run, Hungry Shark, Angry Birds, etc… they all link to your gamertag, as they should.
