A game service computing machine, comprising:

• a logic machine;
• and
• a storage machine holding instruction executable by a logic machine to:
• after release of a video game for execution on a user gaming machine, receive, via a computer network from a developer computing machine different than the user gaming machine, a command to replace initial achievement criteria for awarding an achievement with updated achievement criteria for awarding the achievement;
• receive, from the user gaming machine via the computer network, game data of the video game;
• computer-generate a game statistic for the video game based on the game data;
• and
• if the game statistic meets the updated achievement criteria, award the achievement.

A method of managing game data of a video game at a game service computing machine, the method comprising:

• after release of the video game for execution on a user gaming machine, receiving, via a computer network from a developer computing machine different than the user gaming machine, a command to replace initial achievement criteria for awarding an achievement with updated achievement criteria for awarding the achievement;
• recognizing a game statistic for the video game, the game statistic computer-generated based on game data resulting from execution of the video game on the user gaming machine;
• and
• if the game statistic meets the updated achievement criteria, awarding the achievement.
