I would like to create a service that provide users with relevant data to improve the game play. I would like to track some event + data. For an example match start/end, number of headshots per match ...etc.

I would like to start with CS2, Rainbow six ...etc. Need to add some more games in near future.

How can I develop a program that can track similar data.

Thank you..

The games already have telemetry systems that do it. They are not public information, but the companies have that data and much more.

@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, game-stats, vginsights… but they're unlikely to approve your using their data to do what you're trying to do. A third option: figure out how those companies do what they do without illegal hacking. Have you looked into those extant game stats companies, what info they collect, how they collect it…?
