As we know, Age of Empires: Definitive Edition finally landed on Steam and Age II: DE has a release date. Also, Microsoft is more open to release their games on Steam platform on day one, what we will see with Gears 5.
But… Gears 5 or Halo: The Master Chief Collection will have Xbox Live support with all its features (saves, Achievements, friends, one unified account) which will be a great complement for these games. Age of Empires, as one of the most famous Microsoft’s franchise, doesn’t have and won’t have Xbox Live support on Steam.
Why?! It could be even available as a additional option for gamers, not something compulsory for everyone on Steam. I think, as a AoE team, you should really consider this. Xbox game without all Xbox feature, even on third-party platform? So shame. I would really like to unlock some Achievements in this game throughout Steam.
