Which achievement/achievement tracking system to choose?

Question

Startups

It is necessary to keep records of the achievements of the N-th number of people and record the quantitative results of these achievements in the form of "achievements". I want to prescribe all achievements in advance (with a breakdown by "classes" of users), and then mark them after the achievement.

Answer 2

For computers there is Steam , for mobile phones Google Play Game Services and Game Center , on consoles there are achievements. For browser games, large sites like Kongregate also have their own APIs. Are you sure the platform is not important?
