@frob Anyway we can access those?

You could ask the publishers for permission and cooperation with your plan. But it's unlikely they'd want to share their metrics with you. Or you could look into the independent sites that track game stats, like gameanalytics, tracker network, newzoo,…

I've seen many people suffering when it comes to creating more complex attribute systems for games, in particular RPG and Strategy ones. Dealing with multiple entities and formulas can be daunting.

For that matter, i decided to share a simple library that handles that in an event and data-driven way…

We used Google Analytics some years ago with great success, but there are many similar platforms. “Analytics” is the key word and then you can throw “games” or “mobile” in there.
