Analytics Tracking

[blazing scaffold]

What did you find dodgy about their docs?

GameAnalytics aside and more analytics in general - for multiplayer games I've seen both.

There are certain titles were they care more about what individual users do (e.g.: how often they are online, for how long, etc) and therefore they track things client side.

But I've also seen projects were they care more about what they achieve as a team (level progression, timings)

So I would really treat it as a case-by-case basis. Also you can do both! You can track some events like login, button clicks client-side and more gameplay things server-side
