It’s been confirmed for a while that Hitman 3 will have achievements on EGS. I will admit though not every game has achievements, so it’s partially due to a communication problem that not everyone will know about it.
Weirdly enough I think this is because they share two file asset parts. I could be wrong though but it’s not as consistent to find the game directory as one may think.
Maybe by community design rather, but surely not the internet. I think you’re overreacting on that part.
I’m not sure entirely on this front, but what I will say is it’s been consistent with both modding and community aspects that people will either not play the game further or issue a refund on it. I believe this is because nobody has the time or the energy to pursue and request change to something.
Lastly, I don’t believe there are any plans for IOI to reconsider dropping their contract with EGS. It seems as though some people are pissed that a poorly optimised launcher with bad security features can’t be the bearer of some because that’s just how it is with most people in the community. One mans moral decay of video games is another’s pristine collection of possessions, and yet all I ever see out of it is how bad of a launcher is because they don’t want to play the game for a year. Maybe I’m just being cynical, but that’s just how it is for both worlds sadly.
