Xbox One allows developers to add Achievements to games post-release without bundling them up as DLC, but Microsoft has taken steps to ensure that players who want 100% Gamerscore aren't "constantly overwhelmed" with new Achievements.
These can be doled out at weekly, monthly and quarterly intervals, to reward long-term interest in a game and respond to community developments. Microsoft is "mindful" that completionists may find this annoying, Xbox Live's principal program manager Chad Gibson commented, as part of today's mammoth feature on Xbox One Achievements.
"We're mindful of it, and the corollary is that with a lot of games today, three updates later it's a nice evolution of that game - it's a different game that's been modified and adjusted, based on what people are enjoying and having fun with. And we think that Achievements should match that."
"Especially if a game's been on the market for a while, and they have the opportunity to add all these new Achievements - if you start playing a game a year after it ships, there's probably 2000 Gamerscore to get for that game or more. And so, for the completionists, they're going to have more work to do."
Microsoft remains "super-sensitive to people who are worried about wanting to get all of the Gamerscore," according to Gibson. "We still have policies for developers to make sure that things don't get out of control. Like, we do not want a game offering 10,000 Gamerscore every day. We still have policies, so that user experiences are rational - users have an opportunity to complete everything without feeling constantly overwhelmed.
"A game developer could just take its Gamerscore budget and just, you know, dole it out every week if they wanted to. But, we don't want things to be out of control from a gamer perspective. We don't want people to be constantly overwhelmed with thousands and thousands of things for this game."
