Xbox One vs PS4 vs Wii U - Tråden [//Mod fixat rubrik]

Along with Gamerscore, players can now unlock digital artwork, characters, and stats through achievements.
Applications and media can now take advantage of awarding console users achievments (will not affect Gamerscore).
Achievements and Challenges:
There are now challenges, in addition to achievements.
Achievements are not changing, will remain the same.
Challenges are opportunities that can come and go; They can be a goal or reward.
Challenges can be used to unlock things during a specific time.
Similarities:
You can unlock them and win their rewards.
Once unlocked, they are saved to your achievement history.
They each have an icon to visualize the cool thing you did.
They often are associated with a Game DVR capture to show your friends that you are better than they are.
Developers can release more of them after the game’s initial release (more on that in a bit).
Differences:
Challenges are time based. As just noted, challenges are only available for a certain period of time. Only your activity during that timeframe will count toward unlocking the challenge. Achievements do not expire, so you can unlock them at your leisure.
Challenges do not give out Gamerscore. We want everyone to have the same shot at increasing their Gamerscore to its highest potential. Since challenges are intentionally temporary (an opportunity) and achievements never expire (a promise), only achievements may offer Gamerscore as a reward.
Challenges may cross titles, but achievements cannot. Achievements cannot be shared across titles whereas challenges are allowed to span multiple titles.
Challenges can be unlocked by the community. Community challenges are typically goals that exceed what a lone player can accomplish in the given period of time. Imagine, for example, a game releases a headshot weekend challenge that requires players to cumulatively headshot 1 million baddies in a 3 day period. And every person who participates and meets the challenge’s goals gets the unlock on his or her achievement history and reaps its reward.
Achievements run on the cloud, allowing these features:
Allows Developers to run challenges across all players of a game simultaneously.
Developers can continue to add achievements after initial game release.
Get new achievements without being forced to purchase new content.
Lets developers monitor statistics of achievements and can respond with content to the interest of those players.
Most importantly, this allows developers to involve the community in the development.
